Lets's calculate LCM of 21,31,44,515

Given numbers has no common factors except 1. So, there LCM is their product i.e 14751660

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/14751660

Therefore, the GCF of Fractions 70/21,37/31,11/44,54/515 is 1/14751660

Least Common Multiple of 21,31,44,515 with GCF Formula

Least Common Multiple of 21,31,44,515 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 21,31,44,515 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,31,44,515) = 1

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

GCF(21,31,44,515) x common factors =1 x 1 = 1

LCM(21,31,44,515) = ( 21 × 31 × 44 × 515 ) / 1

LCM(21,31,44,515) = 14751660 / 1

LCM(21,31,44,515) = 14751660
