What is the lcm of 20 and 45

They are: LCM = 120 and hcf = 8

The HCF = 20 The LCM = 600

The LCM is 360.

GCF is 60, LCM is 900

The LCM is 720.

LCM of 15 120 180 is 360.

No, that is the HCF. The LCM is 1800

The LCM is 600. The GCF is 20.

The GCF is 3. The LCM is 120.

HCF(36, 50) = 2LCM(36, 50) = 180

HCF is the highest common factor of two or more numbers. One such pair which has 60 as their HCF can be: 120 and 180.

What is the lcm of 21 and 75

The GCF is 60.

The GCF is 20.

Write 100 and 120 in their prime compositions in power form: 100 = 223052 120 = 233151 For hcf, take lowest power of each prime across the compositions; for LCM, take highest powers: hcf = 223051 = 4 x 1 x 5 = 20 LCM = 233152 = 8 x 3 x 25 = 600

You need at least two numbers to find both of those.

The GCF and LCM of 24 and 60 are 12 and 120 respectively

The LCM of 3, 15 and 36 is 180.

There can be no greatest common multiple. 120 is a common multiple, but then so is 120*10, or 120*100 and so on for ever and ever.The question you are asking is either the Lowest Common Multiple (LCM) or Highest Common Factor (HCF).The LCM is 120 while the HCF is 6

LCM is 20 and the hcf is 10

The LCM is: 1,800

HCF = 5LCM = 440

The HCF is: 2The LCM is: 2,520

The LCM is: 900The HCF is: 10
