The common multiples of 15 and 25 are all multiples of their LCM, which is 75. So, the common multiples are 75, 150, 225, 300, 375, 450, 525, 600, and so on.
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.
The prime factors of 75 are 3 and 5. The prime factorization of 75 is 3 x 5 x 5.
prime numbers can only be multiples of 1 and itself. perhaps 3 is just the number you want.
The factors of 75 are 1, 3, 5, 15, 25 and 75. The prime factors are 3 and 5.
