LCM of:

Least Common Multiple of 405/421,311/620

Given numbers are 405/421,311/620

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 405,311

Least Common Multiple of Numerators i.e. LCM of 405,311 is 125955.

GCF of Denominators means GCF of 421,620 as per the given fractions.

GCF of 421,620 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 405,311

LCM of Fractions 405/421,311/620 is 125955

Given numbers has no common factors except 1. So, there LCM is their product i.e 125955

Least Common Multiple of 405,311 with GCF Formula

Least Common Multiple of 405,311 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 405,311 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(405,311) = 1

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

GCF(405,311) x common factors =1 x 1 = 1

LCM(405,311) = ( 405 × 311 ) / 1

LCM(405,311) = 125955 / 1

LCM(405,311) = 125955


Lets's calculate GCF of 421,620

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 125955/1

Therefore the LCM of Fractions 405/421,311/620 is 125955
