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.
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
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 Least Common Multiple (LCM) for 72 252 is 504.The Highest Common Factor (HCF) for 72 252 is 36.
441 / 252 = 1 r 189 252 / 189 = 1 r 63 189 / 63 = 3 r 0 The hcf of 441 and 252 is 63
332
The greatest common factor of 252 and 300 is 12.
The Greatest Common Factor (GCF) of 90, 120, and 252 is 6.
The GCF of 210, 252, and 294 is 42
The greatest common factor of 108 and 252 is 36.
42
It is: 36
It is: 42
The greatest common factor of 126 and 252 is 126.Always start with finding out if your lower number is a factor of the higher number. Since 126 is a factor of itself (1, 126) and a factor of 252 (2, 126) it is your GCF.
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.Since 252 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 252 is 252
The GCF is 7.
The GCF is 18.
The GCF is 12.
