LCM of:

Least Common Multiple of 49/240,79/440

Given numbers are 49/240,79/440

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 49,79

Least Common Multiple of Numerators i.e. LCM of 49,79 is 3871.

GCF of Denominators means GCF of 240,440 as per the given fractions.

GCF of 240,440 is 40 as it is the largest common factor for these numbers.

Lets's calculate LCM of 49,79

LCM of Fractions 49/240,79/440 is 3871/40

Given numbers has no common factors except 1. So, there LCM is their product i.e 3871

Least Common Multiple of 49,79 with GCF Formula

Least Common Multiple of 49,79 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 49,79 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(49,79) = 1

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

GCF(49,79) x common factors =1 x 1 = 1

LCM(49,79) = ( 49 × 79 ) / 1

LCM(49,79) = 3871 / 1

LCM(49,79) = 3871


Lets's calculate GCF of 240,440

2 240, 440
2 120, 220
2 60, 110
5 30, 55
6, 11

∴ So the GCF of the given numbers is 2 x 2 x 2 x 5 = 40

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3871/40

Therefore the LCM of Fractions 49/240,79/440 is 3871/40
