LCM of:

Least Common Multiple of 639/40,690/9022

Given numbers are 639/40,690/9022

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 639,690

Least Common Multiple of Numerators i.e. LCM of 639,690 is 146970.

GCF of Denominators means GCF of 40,9022 as per the given fractions.

GCF of 40,9022 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 639,690

LCM of Fractions 639/40,690/9022 is 73485

3 639, 690
213, 230

∴ So the LCM of the given numbers is 3 x 213 x 230 = 146970

Least Common Multiple of 639,690 with GCF Formula

Least Common Multiple of 639,690 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 639,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(639,690) = 3

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

GCF(639,690) x common factors =3 x 1 = 3

LCM(639,690) = ( 639 × 690 ) / 3

LCM(639,690) = 440910 / 3

LCM(639,690) = 146970


Lets's calculate GCF of 40,9022

2 40, 9022
20, 4511

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 146970/2

Therefore the LCM of Fractions 639/40,690/9022 is 73485
