Lets's calculate LCM of 14,13,421

Given numbers has no common factors except 1. So, there LCM is their product i.e 76622

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/76622

Therefore, the GCF of Fractions 77/14,78/13,784/421 is 1/76622

Least Common Multiple of 14,13,421 with GCF Formula

Least Common Multiple of 14,13,421 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 14,13,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(14,13,421) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(14,13,421) x common factors =1 x 1 = 1

LCM(14,13,421) = ( 14 × 13 × 421 ) / 1

LCM(14,13,421) = 76622 / 1

LCM(14,13,421) = 76622
