Lets's calculate LCM of 71,36,693

3 71, 36, 693
3 71, 12, 231
71, 4, 77

∴ So the LCM of the given numbers is 3 x 3 x 71 x 4 x 77 = 196812

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/196812

Therefore, the GCF of Fractions 408/71,207/36,505/693 is 1/196812

Least Common Multiple of 71,36,693 with GCF Formula

Least Common Multiple of 71,36,693 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 71,36,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(71,36,693) = 1

common factors(in case of two or more numbers have common factors) = 9

GCF(71,36,693) x common factors =1 x 9 = 9

LCM(71,36,693) = ( 71 × 36 × 693 ) / 9

LCM(71,36,693) = 1771308 / 9

LCM(71,36,693) = 196812
