LCM of:

Least Common Multiple of 398/36,415/1521

Given numbers are 398/36,415/1521

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 398,415

Least Common Multiple of Numerators i.e. LCM of 398,415 is 165170.

GCF of Denominators means GCF of 36,1521 as per the given fractions.

GCF of 36,1521 is 9 as it is the largest common factor for these numbers.

Lets's calculate LCM of 398,415

LCM of Fractions 398/36,415/1521 is 165170/9

Given numbers has no common factors except 1. So, there LCM is their product i.e 165170

Least Common Multiple of 398,415 with GCF Formula

Least Common Multiple of 398,415 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 398,415 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(398,415) = 1

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

GCF(398,415) x common factors =1 x 1 = 1

LCM(398,415) = ( 398 × 415 ) / 1

LCM(398,415) = 165170 / 1

LCM(398,415) = 165170


Lets's calculate GCF of 36,1521

3 36, 1521
3 12, 507
4, 169

∴ So the GCF of the given numbers is 3 x 3 = 9

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 165170/9

Therefore the LCM of Fractions 398/36,415/1521 is 165170/9
