Least Common Multiple of 787/40,506/7820

Given numbers are 787/40,506/7820

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 787,506

Least Common Multiple of Numerators i.e. LCM of 787,506 is 398222.

GCF of Denominators means GCF of 40,7820 as per the given fractions.

GCF of 40,7820 is 20 as it is the largest common factor for these numbers.

Lets's calculate LCM of 787,506

LCM of Fractions 787/40,506/7820 is 398222/20

Given numbers has no common factors except 1. So, there LCM is their product i.e 398222

Least Common Multiple of 787,506 with GCF Formula

Least Common Multiple of 787,506 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 787,506 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(787,506) = 1

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

GCF(787,506) x common factors =1 x 1 = 1

LCM(787,506) = ( 787 × 506 ) / 1

LCM(787,506) = 398222 / 1

LCM(787,506) = 398222


Lets's calculate GCF of 40,7820

2 40, 7820
2 20, 3910
5 10, 1955
2, 391

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 398222/20

Therefore the LCM of Fractions 787/40,506/7820 is 398222/20
