Lets's calculate LCM of 66,76,53,429

2 66, 76, 53, 429
3 33, 38, 53, 429
11 11, 38, 53, 143
1, 38, 53, 13

∴ So the LCM of the given numbers is 2 x 3 x 11 x 1 x 38 x 53 x 13 = 1728012

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1728012

Least Common Multiple of 66,76,53,429 with GCF Formula

Least Common Multiple of 66,76,53,429 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 66,76,53,429 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,76,53,429) = 1

common factors(in case of two or more numbers have common factors) = 66

GCF(66,76,53,429) x common factors =1 x 66 = 66

LCM(66,76,53,429) = ( 66 × 76 × 53 × 429 ) / 66

LCM(66,76,53,429) = 114048792 / 66

LCM(66,76,53,429) = 1728012
