Least Common Multiple of 901/420,768/620

Given numbers are 901/420,768/620

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 901,768

Least Common Multiple of Numerators i.e. LCM of 901,768 is 691968.

GCF of Denominators means GCF of 420,620 as per the given fractions.

GCF of 420,620 is 20 as it is the largest common factor for these numbers.

Lets's calculate LCM of 901,768

LCM of Fractions 901/420,768/620 is 691968/20

Given numbers has no common factors except 1. So, there LCM is their product i.e 691968

Least Common Multiple of 901,768 with GCF Formula

Least Common Multiple of 901,768 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 901,768 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(901,768) = 1

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

GCF(901,768) x common factors =1 x 1 = 1

LCM(901,768) = ( 901 × 768 ) / 1

LCM(901,768) = 691968 / 1

LCM(901,768) = 691968


Lets's calculate GCF of 420,620

2 420, 620
2 210, 310
5 105, 155
21, 31

∴ So the GCF of the given numbers is 2 x 2 x 5 = 20

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 691968/20

Therefore the LCM of Fractions 901/420,768/620 is 691968/20
