Greatest Common Factor

We found the factors 399,588,250 . The biggest common factor number is the GCF number.
So the greatest common factor 399,588,250 is 1.

Lets's calculate LCM of 42,20,504

2 42, 20, 504
2 21, 10, 252
3 21, 5, 126
7 7, 5, 42
1, 5, 6

∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 1 x 5 x 6 = 2520

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2520

Therefore, the GCF of Fractions 399/42,588/20,250/504 is 1/2520

Least Common Multiple of 42,20,504 with GCF Formula

Least Common Multiple of 42,20,504 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 42,20,504 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,20,504) = 2

common factors(in case of two or more numbers have common factors) = 84

GCF(42,20,504) x common factors =2 x 84 = 168

LCM(42,20,504) = ( 42 × 20 × 504 ) / 168

LCM(42,20,504) = 423360 / 168

LCM(42,20,504) = 2520
