Question

Find the biggest number which can divide both 324 and 144?​

Answer 1

Answer:

36

Step-by-step explanation:

To find the HCF or Highest Common Factor of 324 and 144, we do prime factorization of these numbers.

Prime Factorization of 324:- 2×2×3×3×3×3

Prime Factorization of 144:- 2×2×2×2×3×3

To find the HCF, multiply all the factors common to both the numbers-

=> HCF= 2×2×3×3 = 36

So, your answer is 36.
