Best Answer

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.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 126, 210, and 252 is 42

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.

126+126=252

The Least Common Multiple (LCM) for 72 252 is 504.The Highest Common Factor (HCF) for 72 252 is 36.

252 is the LCM of 21, 84, and 126.
