Are all the factors of 72 are multiples of the prime factors of 72?
Apart from 1, all of the other factors of 72 are multiples of prime factors.
What are all the common multiples from 1 to 100 for 7 and 11?
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.
What are the multiples that 30 and 36 have in common?
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...
What are all the common factors of 24and 36?
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.
What are the common multiples of 147 and 2500?
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.).
