42, 84, 126, 168, 210, 252, 294, 336, 378, 420, 462, 504, 546, . . .
1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
You multiply 126 x 2 = 252
The GCF of 210, 252, and 294 is 42
It is: 42
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
Write down all the factors of 108 and 252. Hence 2)108 2)54 3)27 3)9 3)3 = & 2)252 2)126 2)63 3)21 3)7 7)7 = 1 '2' appears in both division sets twice; 2 x 2 = 4 '3' appears in both division sets twice also 3 x 3 = 9 Hence 3 x 9 = 36 Hence '36' is the HCF. NB The '7' and the remaining '3' are NOT common to both sets, so they cannot be part of the HCF.
The HCF is: 12
7
The GCF is 36.
If the highest common factor of 120 and 252 is 12 10*12 = 120 21*12 = 252 Then it follows that the highest common factor of CXX and CCLII is XII X*XII = CXX XXI*XII = CCLII
Well, let's paint a happy little picture with numbers! The LCM (Least Common Multiple) of 72 and 252 is 504, and the HCF (Highest Common Factor) is 36. These numbers are like colors on our palette, each serving a unique purpose in our mathematical landscape. Just remember, there are no mistakes in math, only happy little miscalculations waiting to be corrected.

To find the highest common factor (HCF) of 196 and 252, we first need to find the factors of each number. The factors of 196 are 1, 2, 4, 7, 14, 28, 49, 98, and 196. The factors of 252 are 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, and 252. The highest common factor of 196 and 252 is 28, as it is the greatest number that divides both 196 and 252 without leaving a remainder.
The greatest common factor of 252 and 300 is 12.
