So the greatest common factor 17,72,73 is 1.

Lets's calculate LCM of 79,78,432

2 79, 78, 432
3 79, 39, 216
79, 13, 72

∴ So the LCM of the given numbers is 2 x 3 x 79 x 13 x 72 = 443664

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/443664

Therefore, the GCF of Fractions 17/79,72/78,73/432 is 1/443664

Least Common Multiple of 79,78,432 with GCF Formula

Least Common Multiple of 79,78,432 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 79,78,432 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(79,78,432) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(79,78,432) x common factors =1 x 6 = 6

LCM(79,78,432) = ( 79 × 78 × 432 ) / 6

LCM(79,78,432) = 2661984 / 6

LCM(79,78,432) = 443664
