Any number whose prime factorization includes 5 and 23 is a multiple of 115.
115 = 5 x 23
230 = 2 x 5 x 23
345 = 3 x 5 x 23
460 = 2 x 2 x 5 x 23
575 = 5 x 5 x 23
690 = 2 x 3 x 5 x 23
30 and 60
The factors of 30 and 60 include the prime numbers 2, 3, and 5.
30 and 90 are two of many numbers whose prime factors include 2, 3, and 5.
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 = 30 2 x 2 x 3 x 5 = 60
The prime factorization of 15 is 3 x 5 because three and five are the only prime numbers whose product is 15.
30 and 60

There are not two prime numbers whose product is 64. The prime factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2, which is 2 to the 6th power. These are the only prime numbers that can be multiplied together to result in 64. There are six of them, not two. The only pair of numbers whose product is 64 that includes one prime number is 2 x 32, but only one number is prime.
This question feels incomplete, but as written the LCM is 2.
The prime factorization of 76 is 2 x 2 x 19
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.
