To find the GCF of two numbers, you first need to break them down into their prime factors. For 140 and 252, these are:
140 = 2x2x5x7
252 = 2x2x3x3x7
The next step is to identify common prime factors. In this case, both numbers have two 2s and a 7 in their prime factors. To find the GCF, we simply multiply these common prime factors together:
2x2x7 = 28.
Thus the greatest common factor of 140 and 252 is 28.

What is the greatest common factor 7 21 42 126 252 756?
The greatest common factor must be a factor of the smallest number. The smallest number is 7. Its factors are 1 and 7. So the greatest common factor must be either 1 or 7. Since 7 is the larger of the two factors, check whether it is a factor of the additional numbers. Since it is, 7 is the greatest common factor.
