Lets's calculate LCM of 3990,7248

LCM of Fractions 3990/520,7248/6412 is 1204980

2 3990, 7248
3 1995, 3624
665, 1208

∴ So the LCM of the given numbers is 2 x 3 x 665 x 1208 = 4819920

Least Common Multiple of 3990,7248 with GCF Formula

Least Common Multiple of 3990,7248 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 3990,7248 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(3990,7248) = 6

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

GCF(3990,7248) x common factors =6 x 1 = 6

LCM(3990,7248) = ( 3990 × 7248 ) / 6

LCM(3990,7248) = 28919520 / 6

LCM(3990,7248) = 4819920


Lets's calculate GCF of 520,6412

2 520, 6412
2 260, 3206
130, 1603

∴ So the GCF of the given numbers is 2 x 2 = 4

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 4819920/4

Therefore the LCM of Fractions 3990/520,7248/6412 is 1204980
