The GCF is 6.
The Greatest Common Factor of 210 and 504 is 42 Prime factors of 210: 2 3 5 7 Prime factors of 504: 2 2 2 3 3 7 The intersection is 2 3 7, which is 42
21, 42, 63, 84, 105, 126, 147, 168, 189, 210, 231, 252, 273, . . .
42 = 21 x 31 x 71 126 = 21 x 32 x 71 210 = 21 x 31 x 51 x 71 Take the lowest power of the common primes: hcf of 42, 126 & 210 is 21 x 31 x 71 = 42.
HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2
