Lets's calculate LCM of 1974,8721

LCM of Fractions 1974/821,8721/742 is 5738418

3 1974, 8721
658, 2907

∴ So the LCM of the given numbers is 3 x 658 x 2907 = 5738418

Least Common Multiple of 1974,8721 with GCF Formula

Least Common Multiple of 1974,8721 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 1974,8721 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1974,8721) = 3

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

GCF(1974,8721) x common factors =3 x 1 = 3

LCM(1974,8721) = ( 1974 × 8721 ) / 3

LCM(1974,8721) = 17215254 / 3

LCM(1974,8721) = 5738418


Lets's calculate GCF of 821,742

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5738418/1

Therefore the LCM of Fractions 1974/821,8721/742 is 5738418
