First, find the prime factorization of the number. For instance, with 45: 45 = 3 * 3 * 5 = 32 * 51 Now, from this prime factorization, any numbers whose prime factorizations do not include these factors is coprime to the number you have.
3000. It contains non-repeating 3 as a factor.
2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
2 x 3 x 5 x 7 x 11 x 13 x 17 = 510,510
The prime factorization of 76 is 2 x 2 x 19
37 is a prime number whose factors are itself and one

3 x 3 x 11 = 99
The prime factorization of a number is the primes whose product gives you that number.126/2 = 6363/3 = 2121/3 = 7The bold numbers are the primes. The prime factorization is just the product of these numbers. In this case: 2 x 3 x 3 x 7.Or simplified:2 x 32 x 7
The prime factorization of 15 is 3 x 5 because three and five are the only prime numbers whose product is 15.
2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
