Factorize the LCM
20 = 2 x 2 x 5
Factorize the HCF
300 = 2 x 2x3x5x5
The HCF is the common factor for both numbers whereas the LCM contains all the unique factors of both numbers.
So, 2 x 2x5 or 20 is a common factor for both numbers.
The factors remaining are 3 and 5.
So, 3 is a factor of one number and 5 is the factor of the second number.
The first number = 20x 3 = 60
The second number = 20x 5 = 100
So 60 and 100 are two numbers
Answer = 60 and 100

How do you find sets of two numbers if HCF and LCM are known?
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
What is the HCF and LCM of 18 and 42?
The LCM is: 126
What is the LCM 10z and 20z?
To find the LCM, you first need to express the numbers as the product of their prime factors. In this case: 10z = 2x5xz 20x = 2x2x5xz The next step is to identify the HCF. In this case that's 2x5xz = 10z. Then you multiply the numbers together and divide by the HCF: 10z x 20z/10z = 20z Thus the LCM of 10z and 20z is 20z.
What is the LCM of 15 25 100?
The LCM is 300.
What is the LCM of 15 and 30 and 50 and 100?
The LCM is 300.
