Their factors are:
125 = 1, 5, 25, 125
100 = 1, 2, 4, 5, 10, 20, 25, 50, 100
making their common factors: 1, 5, 25
Alternative method:
The prime factorisations are:
125 = 53
100 = 22 x 52
Therefore their common factors are the factors of the product of their common primes, ie:
Factors of 52 = 25 ⇒ 1, 5, 25
It is 25 that is the GCF of 100 and 125
1, 5 and 25
It is: 25
The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100The factors of 125 are: 1, 5, 25, 125The common factors are: 1, 5, 25The Greatest Common Factor (GCF) is: 25
The common factors of 125 and 1000 are: 1, 5, 25, and 125
The common factors of 2250 and 125 are: 1, 5, 25, and 125
The factors of 125 are 1, 5, 25, 125. For them to be common, they need to be compared to another set of factors.
