LCM of:

Least Common Multiple of 420/980,905/802

Given numbers are 420/980,905/802

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 420,905

Least Common Multiple of Numerators i.e. LCM of 420,905 is 76020.

GCF of Denominators means GCF of 980,802 as per the given fractions.

GCF of 980,802 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 420,905

LCM of Fractions 420/980,905/802 is 38010

5 420, 905
84, 181

∴ So the LCM of the given numbers is 5 x 84 x 181 = 76020

Least Common Multiple of 420,905 with GCF Formula

Least Common Multiple of 420,905 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 420,905 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,905) = 5

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

GCF(420,905) x common factors =5 x 1 = 5

LCM(420,905) = ( 420 × 905 ) / 5

LCM(420,905) = 380100 / 5

LCM(420,905) = 76020


Lets's calculate GCF of 980,802

2 980, 802
490, 401

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 76020/2

Therefore the LCM of Fractions 420/980,905/802 is 38010
