LCM of:

Least Common Multiple of 428/58,639/4860

Given numbers are 428/58,639/4860

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 428,639

Least Common Multiple of Numerators i.e. LCM of 428,639 is 273492.

GCF of Denominators means GCF of 58,4860 as per the given fractions.

GCF of 58,4860 is 2 as it is the largest common factor for these numbers.

Lets's calculate LCM of 428,639

LCM of Fractions 428/58,639/4860 is 136746

Given numbers has no common factors except 1. So, there LCM is their product i.e 273492

Least Common Multiple of 428,639 with GCF Formula

Least Common Multiple of 428,639 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 428,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(428,639) = 1

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

GCF(428,639) x common factors =1 x 1 = 1

LCM(428,639) = ( 428 × 639 ) / 1

LCM(428,639) = 273492 / 1

LCM(428,639) = 273492


Lets's calculate GCF of 58,4860

2 58, 4860
29, 2430

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 273492/2

Therefore the LCM of Fractions 428/58,639/4860 is 136746
