Lets's calculate LCM of 13,11,211

Given numbers has no common factors except 1. So, there LCM is their product i.e 30173

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30173

Therefore, the GCF of Fractions 912/13,791/11,249/211 is 1/30173

Least Common Multiple of 13,11,211 with GCF Formula

Least Common Multiple of 13,11,211 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 13,11,211 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(13,11,211) = 1

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

GCF(13,11,211) x common factors =1 x 1 = 1

LCM(13,11,211) = ( 13 × 11 × 211 ) / 1

LCM(13,11,211) = 30173 / 1

LCM(13,11,211) = 30173
