2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
The factors of 30 and 60 include the prime numbers 2, 3, and 5.
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.
2 x 3 x 5 x 7 x 11 x 13 x 17 = 510,510
The answer depends on how many prime numbers are whose!
