Lets's calculate LCM of 1781,7989

LCM of Fractions 1781/149,7989/821 is 14228409

Given numbers has no common factors except 1. So, there LCM is their product i.e 14228409

Least Common Multiple of 1781,7989 with GCF Formula

Least Common Multiple of 1781,7989 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 1781,7989 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1781,7989) = 1

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

GCF(1781,7989) x common factors =1 x 1 = 1

LCM(1781,7989) = ( 1781 × 7989 ) / 1

LCM(1781,7989) = 14228409 / 1

LCM(1781,7989) = 14228409


Lets's calculate GCF of 149,821

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 14228409/1

Therefore the LCM of Fractions 1781/149,7989/821 is 14228409
