Lets's calculate LCM of 14,37,235

Given numbers has no common factors except 1. So, there LCM is their product i.e 121730

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/121730

Therefore, the GCF of Fractions 21/14,56/37,456/235 is 1/121730

Least Common Multiple of 14,37,235 with GCF Formula

Least Common Multiple of 14,37,235 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 14,37,235 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(14,37,235) = 1

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

GCF(14,37,235) x common factors =1 x 1 = 1

LCM(14,37,235) = ( 14 × 37 × 235 ) / 1

LCM(14,37,235) = 121730 / 1

LCM(14,37,235) = 121730
