The prime factors of 144 are 2, 2, 2, 2, 3 and 3 The prime factors of 300 are 2, 2, 3, 5 and 5 So the only prime numbers which are common to both numbers are 2, 2 and 3 = 12
The prime factors of 18 are 2, 3 and 3. The prime factors of 42 are 2, 3 and 7. Thus, the prime factors which are common to both are 2 and 3. However, the usual manner of answering this sort of question is to give the greatest common factor which is common to both (or all) numbers, and not only prime factors - so as 2 and 3 are common to both numbers and as 2 x 3 = 6 the 'other' answer to the question is 6.
The prime factors of 144 are 2, 2, 2, 2, 3 and 3 The prime factors of 225 are 3, 3, 5 and 5 The only prime numbers which are common to both are 3 and 3 ... 9
List the numbers: 216, 360 Divide both numbers by 2, since they are both divisible by 2: 108, 180 Divide both numbers by 2 again, since they are both divisible by 2: 54, 90 Divide both numbers by 2 yet again, since they are both divisible by 2: 27, 45 Divide both numbers by 3, since they are both divisible by 3: 9, 15 Divide both numbers by 3 again, since they are both divisible by 3: 3, 5 Since 3 and 5 do not have any common factors greater than 1, we can now multiply all the numbers we divided by: 2 x 2 x 2 x 3 x 3 = 8 x 9 = 72 GCF(216, 360)=72
All numbers having the prime factors 2 and 3 are divisible by both 6 and 2. 6, 12, 18 and so on.
The prime factors of 60 are 2, 2, 3, and 5.The prime factors of 105 are 3, 5, and 7.The prime numbers that are factors of both 60 and 105 are 3 and 5.
The prime factors of 162 are 2 and 3. The prime factorization of 162 is 2 x 3⁴.
Multiples of 6.

The common prime factors of 18 and 36 are 2 and 3. Both numbers can be divided evenly by 2 and 3.
Common factors of both numbers are: 1, 2, 3 and 6
42, 48 are the two numbers bigger than 40 that have 2 and 3 as their only prime factors.
Factors are the numbers you multiply together. For example, in the equation 2 times 3 equals 6, the 2 and the 3 are both factors of 6.
