Factor each number into its prime factors 

24 = 2 x 2 x 2 x 3                                          90 =2 x 3 x 3 x 5

Take the most factors that are common to both factorization a and multiply 

2 x 3 = 6    ANSWER

6 is the greatest common factor of 24 & 90.
the way of find it is as:

First take small no divide biger by it take the remainder(non zero) and divide the smaller by the remainder.
Keep on doing this un till remainder becomes zero .take the divident as greatest common factor.
ex: 90/24==remainder 18,
24/18==remainder 6,
18/6==remainder 0,
g.c.f of 24,90 is 6.

The greatest common factor is sometimes known as the gcf or the gcd (greatest common divisor).

The greatest common factor of 24 and 90 is the largest number that both 24 and 90 can be divided into evenly. That would be 6. It will go into 24 four times and into 90 fifteen times.

Here is another problem. What is the greatest common factor of 18 and 39?

To systematically find the numbers that will divide into both 18 and 39 evenly (without remainders), I start with 1 and work my way up. Of course, 1 can be divided into any round number evenly, but there must be a higher number than 1 that will go into both 18 and 39 evenly! My answer is 3.

Here is another one. 72 and 76. The least common denominator is 4, because it is the highest number that 72
and 76 can be divided into evenly - according to my calculations!
