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.
