Lets's calculate LCM of 890,991

Given numbers has no common factors except 1. So, there LCM is their product i.e 881990

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/881990

Therefore, the GCF of Fractions 172/890,191/991 is 1/881990

Least Common Multiple of 890,991 with GCF Formula

Least Common Multiple of 890,991 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 890,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(890,991) = 1

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

GCF(890,991) x common factors =1 x 1 = 1

LCM(890,991) = ( 890 × 991 ) / 1

LCM(890,991) = 881990 / 1

LCM(890,991) = 881990
