So the greatest common factor 423,925,168 is 1.

Lets's calculate LCM of 42,18,756

2 42, 18, 756
3 21, 9, 378
3 7, 3, 126
7 7, 1, 42
1, 1, 6

∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 1 x 1 x 6 = 756

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/756

Therefore, the GCF of Fractions 423/42,925/18,168/756 is 1/756

Least Common Multiple of 42,18,756 with GCF Formula

Least Common Multiple of 42,18,756 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 42,18,756 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,18,756) = 6

common factors(in case of two or more numbers have common factors) = 126

GCF(42,18,756) x common factors =6 x 126 = 756

LCM(42,18,756) = ( 42 × 18 × 756 ) / 756

LCM(42,18,756) = 571536 / 756

LCM(42,18,756) = 756
