Lets's calculate LCM of 1280,3995

LCM of Fractions 1280/621,3995/844 is 1022720

5 1280, 3995
256, 799

∴ So the LCM of the given numbers is 5 x 256 x 799 = 1022720

Least Common Multiple of 1280,3995 with GCF Formula

Least Common Multiple of 1280,3995 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 1280,3995 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(1280,3995) = 5

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

GCF(1280,3995) x common factors =5 x 1 = 5

LCM(1280,3995) = ( 1280 × 3995 ) / 5

LCM(1280,3995) = 5113600 / 5

LCM(1280,3995) = 1022720


Lets's calculate GCF of 621,844

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1022720/1

Therefore the LCM of Fractions 1280/621,3995/844 is 1022720
