LCM of:

Least Common Multiple of 405/42,4212/752

Given numbers are 405/42,4212/752

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 405,4212

Least Common Multiple of Numerators i.e. LCM of 405,4212 is 21060.

GCF of Denominators means GCF of 42,752 as per the given fractions.

GCF of 42,752 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 405,4212

LCM of Fractions 405/42,4212/752 is 10530

3 405, 4212
3 135, 1404
3 45, 468
3 15, 156
5, 52

∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 5 x 52 = 21060

Least Common Multiple of 405,4212 with GCF Formula

Least Common Multiple of 405,4212 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 405,4212 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(405,4212) = 81

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

GCF(405,4212) x common factors =81 x 1 = 81

LCM(405,4212) = ( 405 × 4212 ) / 81

LCM(405,4212) = 1705860 / 81

LCM(405,4212) = 21060


Lets's calculate GCF of 42,752

2 42, 752
21, 376

∴ So the GCF of the given numbers is 2 = 2

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 21060/2

Therefore the LCM of Fractions 405/42,4212/752 is 10530
