Least Common Multiple of 221/688,630/985,151/247

Given numbers are 221/688,630/985,151/247

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 221,630,151

Least Common Multiple of Numerators i.e. LCM of 221,630,151 is 21023730.

GCF of Denominators means GCF of 688,985,247 as per the given fractions.

GCF of 688,985,247 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 221,630,151

LCM of Fractions 221/688,630/985,151/247 is 21023730

Given numbers has no common factors except 1. So, there LCM is their product i.e 21023730

Least Common Multiple of 221,630,151 with GCF Formula

Least Common Multiple of 221,630,151 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 221,630,151 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(221,630,151) = 1

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

GCF(221,630,151) x common factors =1 x 1 = 1

LCM(221,630,151) = ( 221 × 630 × 151 ) / 1

LCM(221,630,151) = 21023730 / 1

LCM(221,630,151) = 21023730


Lets's calculate GCF of 688,985,247

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 21023730/1

Therefore the LCM of Fractions 221/688,630/985,151/247 is 21023730
