Lets's calculate LCM of 1209,5796

LCM of Fractions 1209/80,5796/120 is 2335788/40

3 1209, 5796
403, 1932

∴ So the LCM of the given numbers is 3 x 403 x 1932 = 2335788

Least Common Multiple of 1209,5796 with GCF Formula

Least Common Multiple of 1209,5796 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 1209,5796 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1209,5796) = 3

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

GCF(1209,5796) x common factors =3 x 1 = 3

LCM(1209,5796) = ( 1209 × 5796 ) / 3

LCM(1209,5796) = 7007364 / 3

LCM(1209,5796) = 2335788


Lets's calculate GCF of 80,120

2 80, 120
2 40, 60
2 20, 30
5 10, 15
2, 3

∴ So the GCF of the given numbers is 2 x 2 x 2 x 5 = 40

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2335788/40

Therefore the LCM of Fractions 1209/80,5796/120 is 2335788/40
