Lets's calculate LCM of 15,20,25

### Least Common Multiple (LCM) of 15,20,25 By Common Division

 5 15, 20, 25 3, 4, 5

∴ So the LCM of the given numbers is 5 x 3 x 4 x 5 = 300

Least Common Multiple of 15,20,25 with GCF Formula

### Least Common Multiple of 15,20,25 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 15,20,25 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,20,25) = 5

common factors(in case of two or more numbers have common factors) = 5

GCF(15,20,25) x common factors =5 x 5 = 25

LCM(15,20,25) = ( 15 × 20 × 25 ) / 25

LCM(15,20,25) = 7500 / 25

LCM(15,20,25) = 300

Lets's calculate GCF of 24,28,32

### Greatest Common Factor (GCF) of 24,28,32 By Common Division

 2 24, 28, 32 2 12, 14, 16 6, 7, 8

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 300/4

Therefore the LCM of Fractions 15/24,20/28,25/32 is 75
