Each vs. Both
Differences
Grammatical Functions
'Each':
As you know, determiners are used before nouns, 'each' is no different and as a determiner, it is used before nouns. 'Each' as a pronoun is used alone without any noun following it. Adverbs are words that can modify adjectives and other adverbs or sometimes they give more information about the verb. 'Each' can be an adverb, too.
I carried each chair under the roof of the store because it was raining outside. → determiner
Each of our teachers is making the students get ready for the exams. → pronoun
They put two boxes beside us and we took one item from each. → adverb
'Both':
'Both' as a determiner is used before nouns and as a pronoun, it is used alone with no nouns following it. As conjunction, 'both' is always followed by the term 'and' that we will discuss in this article.
Both of them ordered sushi. → pronoun
He took both shots of vodka and bent over the counter. → determiner
The doctor did a surgery on both my tooth and jaw. → conjunction
Singular or Plural Nouns?
'Each':
is followed by a singular noun. And as a result, it is used with a singular verb.
Each girl was standing behind the door to try on the shoes.
Each member should sign the contract.
'Both':
is followed by a plural noun or a singular noun which is joined to another singular noun by the term 'and'. In both cases, we are supposed to use a plural verb with the term 'both.'

Both films are exciting.

What They mean
'Each':
means 'every of' things or people. We can use 'each' to refer to every one of the individuals in a group when the members of the group are two or even more than two.
We had five dollars, each.
Each coat cost $70.
'Both':
means two. We use the term 'both' to refer to two things or people at the same time together. Remember, we cannot use the term 'both' when there are more than two members in a group.
Both his wife and his mother are happy with him joining the army.
I had salmon and the shrimp, both.
'Both' + 'Adjective' + 'and' + 'Adjective'
In some cases, adjectives are used after 'both.' Since we cannot make adjectives plural we can link them by the term 'and.' In this case, you are allowed to use a singular verb with the term 'both.' Check out the examples:
The man is both brave and muscular.
The movie we have watched last night was both interesting and frightening.
Similarities
'Both of' and 'Each of'
'Each of' and 'both of':
We are not allowed to use plural nouns or pronouns immediately after the term each.As a result, we use this structure: [ each of + determiner + plural noun] or [ each of + pronoun]. On the contrary, we can use a plural noun immediately after the term 'both,' but whenever we want to use a 'determiner and a plural noun' or a 'plural pronoun,' we can use the phrase 'both of', however, both can be used alone before [determiners + plural nouns] the general structures are: [both + plural noun], [both of + determiner + plural noun], or [both of + plural pronoun].

Now let us take a look at examples to get to know the usage of these structures in a sentence.

Negation
'Each' and 'both'
cannot be used in negative sentences. We mean you cannot use them in sentences that include the term not. So, what if we want to refer to two things in a group or at the same time? The answer to this question is clear. As you know, 'neither' in positive sentences and 'either' in negative sentences imply a negative meaning. So, we can use them instead of 'both' and 'each.'
Either of them is not fit enough. (Not "Each of them is not fit enough.")
Neither her husband nor her father had brown eyes. (Not "Both her husband and her father didn't have brown eyes.")
