Least Common Multiple of 408/70,201/68,340/45

Given numbers are 408/70,201/68,340/45

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 408,201,340

Least Common Multiple of Numerators i.e. LCM of 408,201,340 is 136680.

GCF of Denominators means GCF of 70,68,45 as per the given fractions.

GCF of 70,68,45 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 408,201,340

LCM of Fractions 408/70,201/68,340/45 is 136680

2 408, 201, 340
2 204, 201, 170
3 102, 201, 85
17 34, 67, 85
2, 67, 5

∴ So the LCM of the given numbers is 2 x 2 x 3 x 17 x 2 x 67 x 5 = 136680

Least Common Multiple of 408,201,340 with GCF Formula

Least Common Multiple of 408,201,340 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 408,201,340 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(408,201,340) = 1

common factors(in case of two or more numbers have common factors) = 204

GCF(408,201,340) x common factors =1 x 204 = 204

LCM(408,201,340) = ( 408 × 201 × 340 ) / 204

LCM(408,201,340) = 27882720 / 204

LCM(408,201,340) = 136680


Lets's calculate GCF of 70,68,45

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 136680/1

Therefore the LCM of Fractions 408/70,201/68,340/45 is 136680
