Answer:

  • 180

Step-by-step explanation:

You need to find the HCF of 36 and 90.

Prime factors of each:

  • 36 = 2*2*3*3
  • 90 = 2*3*3*5

HCF includes all prime factors of both numbers:

  • HCF(36, 90) = 2*2*3*3*5 = 180

To find the least number,

Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.

→ 36 = 2 × 2 × 3 × 3

→ 90 = 2 × 3 × 3 × 5

Then the required HCF will be,

→ 2 × 2 × 3 × 3 × 5

→ 180 (HCF)

Thus, 180 is the least number which is exactly divisible by 36 and 90.
