Lets's calculate LCM of 409,5704

LCM of Fractions 409/690,5704/3970 is 2332936/10

Given numbers has no common factors except 1. So, there LCM is their product i.e 2332936

Least Common Multiple of 409,5704 with GCF Formula

Least Common Multiple of 409,5704 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 409,5704 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(409,5704) = 1

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

GCF(409,5704) x common factors =1 x 1 = 1

LCM(409,5704) = ( 409 × 5704 ) / 1

LCM(409,5704) = 2332936 / 1

LCM(409,5704) = 2332936


Lets's calculate GCF of 690,3970

2 690, 3970
5 345, 1985
69, 397

∴ So the GCF of the given numbers is 2 x 5 = 10

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2332936/10

Therefore the LCM of Fractions 409/690,5704/3970 is 2332936/10
