LCM of:

Least Common Multiple of 490/405,163/765

Given numbers are 490/405,163/765

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 490,163

Least Common Multiple of Numerators i.e. LCM of 490,163 is 79870.

GCF of Denominators means GCF of 405,765 as per the given fractions.

GCF of 405,765 is 45 as it is the largest common factor for these numbers.

Lets's calculate LCM of 490,163

LCM of Fractions 490/405,163/765 is 79870/45

Given numbers has no common factors except 1. So, there LCM is their product i.e 79870

Least Common Multiple of 490,163 with GCF Formula

Least Common Multiple of 490,163 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 490,163 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(490,163) = 1

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

GCF(490,163) x common factors =1 x 1 = 1

LCM(490,163) = ( 490 × 163 ) / 1

LCM(490,163) = 79870 / 1

LCM(490,163) = 79870


Lets's calculate GCF of 405,765

3 405, 765
3 135, 255
5 45, 85
9, 17

∴ So the GCF of the given numbers is 3 x 3 x 5 = 45

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 79870/45

Therefore the LCM of Fractions 490/405,163/765 is 79870/45
