The factors of 27 are:
1, 3, 9, 27
The factors of 57 are:
1, 3, 19, 57
The factors of 97 are:
1, 97
The factors of 98 are:
1, 2, 7, 14, 49, 98
97 is not divisible by 4.
97 is not divisible by 5.
57 + z = 97 z = 97 - 57 z = 40
97 is only divisible by itself and one because it is a prime number
No. 97 is not evenly divisible by 40.
1
No.
23, 97 and 47 are prime numbers. They are only divisible by them and 1 number.
27/97 is in its simplest form.
57 is the only composite number is the list.
To be sure, prime numbers are a number which cannot be divisible by every number except for itself and one. Take 5 for an example. There is no possible number which is divisible by itself except for itself and one. So, 5 is a prime number.2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 are all prime numbers to 100. Let's refresh our mind. Now, 57 has factors of 1, 3, 19, and 57. Let's remove the 57 and 1. Now, 3 and 19 are all the factors of 57.
291 is not prime. It is at least divisible by 3 and 97. This makes it not prime since all prime numbers must only be divisible by 1 and itself.
