Apart from 1, all of the other factors of 72 are multiples of prime factors.

77 is the only one. 7 and 11 are both prime numbers, which means they must also be relatively prime (no common factors), so their least common multiple is 77.

In order to find the common multiples of two numbers you first need to express them as the product of their prime factors: 30 = 2x3x5 36 = 2x2x3x3 The next step is to identify any common factors. In this case, both numbers have a 2 and a 3 as prime factors, so we can discard one of each. Take all the remaining prime factors (2, 2, 3, 3 and 5) and multiply them together to get the LCM: 2x2x3x3x5 = 180. To find other multiples that 30 and 36 have in common, you multiply this number by any integer (2, 3, 4...) Thus the first few common multiples of 30 and 36 are: 180, 360, 540, 720...

The prime factors of 24 are 2,2,2 and 3 The prime factors of 36 are 2,2,3 and 3 Thus the common factors are 1,2,3,4,6 and 12.

147 and 2500 have no common factors other than 1, so their common multiples are their product, 367,500, and all multiples of 367,500 (735,000, 1,102,500, 1,470,000, 1,837,500, etc.).

yes because it helps me figure out all the prime numbers!;)

All of them except "1."

35 and 70 both have 7 and 5 as prime factors

All numbers have common multiples.

There are infinitely many prime factors.

To find common multiples of two numbers, you first have to break them down into their prime factors. In this case, the prime factors of 30 and 75 are: 30 = 2x3x5 75 = 3x5x5 The next step is to identify and discard any duplicate common factors. In this case both numbers have a 3 and a 5 as prime factors, so we can discard one of each. Taking all the other prime factors (2, 3, 5 and 5) and multiplying them together will give us the LCM: 2x3x5x5 = 150. Thus the lowest common multiple of 30 and 75 is 150. To find other common multiples, you just multiply this LCM by any integer. For instance, 150x2, 150x3, 150x4 and so on. This means the first few common multiples of 30 and 75 are 150, 300, 450 and 600.

77 is the only one. 7 and 11 are both prime numbers, which means they must also be relatively prime (no common factors), so their least common multiple is 77.
