The Greatest Common Factor of 12, 16, 24: 4

Write the prime composition of the numbers in power form and take the lowest power of each prime across all the numbers; if a prime does not exist in a number, its power in that number is zero (any number to the power zero is 1):

12: 2^2 x 3^1

16: 2^4

24: 2^3 x 3^1

gcf = 2^2 x 3^0

= 4 x 1

= 4
It is 8
