Lets's calculate LCM of 78,403,282

2 78, 403, 282
3 39, 403, 141
13 13, 403, 47
1, 31, 47

∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 31 x 47 = 113646

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/113646

Therefore, the GCF of Fractions 7/78,34/403,42/282 is 1/113646

Least Common Multiple of 78,403,282 with GCF Formula

Least Common Multiple of 78,403,282 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 78,403,282 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,403,282) = 1

common factors(in case of two or more numbers have common factors) = 78

GCF(78,403,282) x common factors =1 x 78 = 78

LCM(78,403,282) = ( 78 × 403 × 282 ) / 78

LCM(78,403,282) = 8864388 / 78

LCM(78,403,282) = 113646
