Lets's calculate LCM of 97,30,31

Given numbers has no common factors except 1. So, there LCM is their product i.e 90210

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/90210

Therefore, the GCF of Fractions 60/97,15/30,429/31 is 3/90210

Least Common Multiple of 97,30,31 with GCF Formula

Least Common Multiple of 97,30,31 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 97,30,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(97,30,31) = 1

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

GCF(97,30,31) x common factors =1 x 1 = 1

LCM(97,30,31) = ( 97 × 30 × 31 ) / 1

LCM(97,30,31) = 90210 / 1

LCM(97,30,31) = 90210
