## Is 215 prime or composite?

215 is a composite number. The exponents in the prime factorization are 1 and 1.

## Is 2 and 3 Coprime numbers?

Every prime number is co-prime to each other: As every prime number has only two factors 1 and the number itself, the only common factor of two prime numbers will be 1. For example, 2 and 3 are two prime numbers. … The only common factor is 1 and hence is co-prime.

## What are the factors of 216 and 215?

The factors of 216 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108 and 216. The factors of 215 are 1, 5, 43 and 215. So, the Greatest Common Factor for these numbers is 1 because it divides all them without a remainder.

## What are the multiples of 215?
