Lets's calculate LCM of 77,401,169

LCM of Fractions 77/649,401/689,169/658 is 5218213

Given numbers has no common factors except 1. So, there LCM is their product i.e 5218213

Least Common Multiple of 77,401,169 with GCF Formula

Least Common Multiple of 77,401,169 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 77,401,169 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,401,169) = 1

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

GCF(77,401,169) x common factors =1 x 1 = 1

LCM(77,401,169) = ( 77 × 401 × 169 ) / 1

LCM(77,401,169) = 5218213 / 1

LCM(77,401,169) = 5218213


Lets's calculate GCF of 649,689,658

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5218213/1

Therefore the LCM of Fractions 77/649,401/689,169/658 is 5218213
