# Least Common Multiple of 10, 20, 55, 40, 45

Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 10, 20, 55, 40, 45 i.e. 3960 smallest integer divisible by all numbers.

Least common multiple (LCM) of 10, 20, 55, 40, 45 is 3960.

LCM(10, 20, 55, 40, 45) = 3960

## LCM of 10, 20, 55, 40, 45

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

### Least Common Multiple (LCM) of 10,20,55,40,45 By Common Division

 2 10, 20, 55, 40, 45 2 5, 10, 55, 20, 45 5 5, 5, 55, 10, 45 1, 1, 11, 2, 9

∴ So the LCM of the given numbers is 2 x 2 x 5 x 1 x 1 x 11 x 2 x 9 = 3960

### Least Common Multiple of 10,20,55,40,45 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 10,20,55,40,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(10,20,55,40,45) = 5

common factors(in case of two or more numbers have common factors) = 1000

GCF(10,20,55,40,45) x common factors =5 x 1000 = 5000

LCM(10,20,55,40,45) = ( 10 × 20 × 55 × 40 × 45 ) / 5000

LCM(10,20,55,40,45) = 19800000 / 5000

LCM(10,20,55,40,45) = 3960

∴ Least Common Multiple of 10,20,55,40,45 is 3960
