Lets's calculate LCM of 16,375

Lowest Common Multiple of 16,375 using Common Division

Given numbers has no common factors except 1. So, there LCM is their product i.e 6000

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/6000

Therefore, the GCF of Fractions 390/16,630/375 is 30/6000

Least Common Multiple of 16,375 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 16,375 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(16,375) = 1

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

GCF(16,375) x common factors =1 x 1 = 1

LCM(16,375) = ( 16 × 375 ) / 1

LCM(16,375) = 6000 / 1

LCM(16,375) = 6000
