LCM of:

Least Common Multiple of 640/58,697/9920

Given numbers are 640/58,697/9920

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 640,697

Least Common Multiple of Numerators i.e. LCM of 640,697 is 446080.

GCF of Denominators means GCF of 58,9920 as per the given fractions.

GCF of 58,9920 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 640,697

LCM of Fractions 640/58,697/9920 is 223040

Given numbers has no common factors except 1. So, there LCM is their product i.e 446080

Least Common Multiple of 640,697 with GCF Formula

Least Common Multiple of 640,697 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 640,697 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(640,697) = 1

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

GCF(640,697) x common factors =1 x 1 = 1

LCM(640,697) = ( 640 × 697 ) / 1

LCM(640,697) = 446080 / 1

LCM(640,697) = 446080


Lets's calculate GCF of 58,9920

2 58, 9920
29, 4960

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 446080/2

Therefore the LCM of Fractions 640/58,697/9920 is 223040
