Least Common Multiple of 672/686,385/985

Given numbers are 672/686,385/985

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 672,385

Least Common Multiple of Numerators i.e. LCM of 672,385 is 36960.

GCF of Denominators means GCF of 686,985 as per the given fractions.

GCF of 686,985 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 672,385

LCM of Fractions 672/686,385/985 is 36960

7 672, 385
96, 55

∴ So the LCM of the given numbers is 7 x 96 x 55 = 36960

Least Common Multiple of 672,385 with GCF Formula

Least Common Multiple of 672,385 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 672,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(672,385) = 7

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

GCF(672,385) x common factors =7 x 1 = 7

LCM(672,385) = ( 672 × 385 ) / 7

LCM(672,385) = 258720 / 7

LCM(672,385) = 36960


Lets's calculate GCF of 686,985

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 36960/1

Therefore the LCM of Fractions 672/686,385/985 is 36960
