Lets's calculate LCM of 94,40,47,812

2 94, 40, 47, 812
2 47, 20, 47, 406
47 47, 10, 47, 203
1, 10, 1, 203

∴ So the LCM of the given numbers is 2 x 2 x 47 x 1 x 10 x 1 x 203 = 381640

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/381640

Therefore, the GCF of Fractions 21/94,95/40,71/47,95/812 is 1/381640

Least Common Multiple of 94,40,47,812 with GCF Formula

Least Common Multiple of 94,40,47,812 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 94,40,47,812 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(94,40,47,812) = 1

common factors(in case of two or more numbers have common factors) = 376

GCF(94,40,47,812) x common factors =1 x 376 = 376

LCM(94,40,47,812) = ( 94 × 40 × 47 × 812 ) / 376

LCM(94,40,47,812) = 143496640 / 376

LCM(94,40,47,812) = 381640
