The greatest common factor (GCF) of two numbers is the largest number that divides both of them without leaving a remainder. To find the GCF of 126 and 315, you can use prime factorization. The prime factorization of 126 is 2 x 3 x 3 x 7, and the prime factorization of 315 is 3 x 3 x 5 x 7. The common factors are 3 and 7, so the GCF of 126 and 315 is 3 x 7 = 21.
To find the greater common factor (GCF) of two ( or more) numbers, factorise each number.
Hence
126
has factors of 2,3,3,7
315
has factors of 3,3,5,7
The common factors are '3' , '3' again and '7'.
Multiply together
3 x 3 x 7 =
9 x 7 = 63 The GCF of 126, & 315.
NB The '2' & '5' are NOT common to both numbers.
the GCF is 105
The GCF is 105.
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 315 and 525 is 105
