Greatest Common Factor

We found the factors 43,36,29,71 . The biggest common factor number is the GCF number.
So the greatest common factor 43,36,29,71 is 1.

Lets's calculate LCM of 42,51,15,636

2 42, 51, 15, 636
3 21, 51, 15, 318
7, 17, 5, 106

∴ So the LCM of the given numbers is 2 x 3 x 7 x 17 x 5 x 106 = 378420

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/378420

Therefore, the GCF of Fractions 43/42,36/51,29/15,71/636 is 1/378420

Least Common Multiple of 42,51,15,636 with GCF Formula

Least Common Multiple of 42,51,15,636 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 42,51,15,636 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,51,15,636) = 3

common factors(in case of two or more numbers have common factors) = 18

GCF(42,51,15,636) x common factors =3 x 18 = 54

LCM(42,51,15,636) = ( 42 × 51 × 15 × 636 ) / 54

LCM(42,51,15,636) = 20434680 / 54

LCM(42,51,15,636) = 378420
