Lets's calculate LCM of 25,268

Lowest Common Multiple of 25,268 using Common Division

Given numbers has no common factors except 1. So, there LCM is their product i.e 6700

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/6700

Therefore, the GCF of Fractions 420/25,624/268 is 12/6700

Least Common Multiple of 25,268 with GCF Formula

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 25,268 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(25,268) = 1

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

GCF(25,268) x common factors =1 x 1 = 1

LCM(25,268) = ( 25 × 268 ) / 1

LCM(25,268) = 6700 / 1

LCM(25,268) = 6700
