How do you find the two numbers if their LCM and HCF is given?

First we need to find the highest common factor (H.C.F.) of 15 and 18 which is 3. Then we need to find the lowest common multiple (L.C.M.) of 15 and 18 which is 90. Therefore, product of H.C.F. and L.C.M. of 15 and 18 = product of 15 and 18.

What is the third proportional to 9 and 12?

16
∴ The third proportional to 9 and 12 is 16.

What is the relationship between LCM and HCF of numbers 60 and 72?

What is the Relation Between LCM and HCF of 60, 72? The following equation can be used to express the relation between LCM and HCF of 60 and 72, i.e. HCF × LCM = 60 × 72.

What is the HCF of 3 and 2?

1
Answer: HCF of 2 and 3 is 1.

What is the LCM of three numbers whose HCF is 3?

The LCM of three numbers is 720 and their HCF is 3. The first number is 15 and the second one is 36. We need to find the third number. Let the third number be N. Its factors must be 3 and some other factors. LCM = 2x2x3x3x5xM = 720, or M = 4. So the third number, N, is 48.

What is the LCM of two numbers?

Lowest Common Factor (LCM) Definition: LCM stands for Lowest or Least Common Multiple. In other words, the LCM of two or more numbers is the smallest positive integer divisible by all the given numbers. Example: Consider this as an example; the LCM of 12 and 15 is 60.

What is the LCM of 12 and 18 using long division?

Example: LCM of the numbers 12 and 18. So, after performing the long division method, you get the LCM of the number 12 and 18 = 2 × 3 × 2 × 3 = 36 LCM and HCF with Co-prime Numbers LCM of the Co – Prime numbers (m, n) = product of two numbers (m, n)

What is the least common multiple of 2 and 3?

LCM or Least common multiple is the smallest number which is divisible by two or more given numbers. For example, LCM of 2 & 3 is 6. What is the GCF of 24 and 36? By prime factorisation, we know;
