Lets's calculate LCM of 77,648,709

LCM of Fractions 77/644,648/734,709/972 is 17688132

Given numbers has no common factors except 1. So, there LCM is their product i.e 35376264

Least Common Multiple of 77,648,709 with GCF Formula

Least Common Multiple of 77,648,709 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 77,648,709 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,648,709) = 1

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

GCF(77,648,709) x common factors =1 x 1 = 1

LCM(77,648,709) = ( 77 × 648 × 709 ) / 1

LCM(77,648,709) = 35376264 / 1

LCM(77,648,709) = 35376264


Lets's calculate GCF of 644,734,972

2 644, 734, 972
322, 367, 486

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 35376264/2

Therefore the LCM of Fractions 77/644,648/734,709/972 is 17688132
