Lets's calculate LCM of 78,26,824

2 78, 26, 824
13 39, 13, 412
3, 1, 412

∴ So the LCM of the given numbers is 2 x 13 x 3 x 1 x 412 = 32136

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/32136

Therefore, the GCF of Fractions 15/78,47/26,517/824 is 1/32136

Least Common Multiple of 78,26,824 with GCF Formula

Least Common Multiple of 78,26,824 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 78,26,824 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,26,824) = 2

common factors(in case of two or more numbers have common factors) = 26

GCF(78,26,824) x common factors =2 x 26 = 52

LCM(78,26,824) = ( 78 × 26 × 824 ) / 52

LCM(78,26,824) = 1671072 / 52

LCM(78,26,824) = 32136
