What are the gcf of number 15 and 45
The greatest common factor of the numbers 15 and 75 is 15.
The GCF of both numbers is 15
The GCF of 75 and 90 is 15.
It is: 15
The greatest common factor of the numbers 45, 75 and 90 is 15.
Factor each number in turn . Hence 3 x 5 = 15 5 x 11 = 55 5 x 5 x 3 = 75 Since '5' appears once in each set of factors , then '5' is the GCF. The LCM common multiple is the highest factors multiplied together. Hence 5 x 5 x 3 x 11 = 825 is the LCM
