Lets's calculate LCM of 29,97,965

Given numbers has no common factors except 1. So, there LCM is their product i.e 2714545

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2714545

Therefore, the GCF of Fractions 21/29,45/97,720/965 is 3/2714545

Least Common Multiple of 29,97,965 with GCF Formula

Least Common Multiple of 29,97,965 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 29,97,965 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(29,97,965) = 1

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

GCF(29,97,965) x common factors =1 x 1 = 1

LCM(29,97,965) = ( 29 × 97 × 965 ) / 1

LCM(29,97,965) = 2714545 / 1

LCM(29,97,965) = 2714545
