Answer 1

Answer:

261 = 3×3×29

639 = 3×3×71

816 = 2×2×2×2×3×17

do answer is 3

Answer 2

Given,

The given numbers are = 261,639,816

To find,

The HCF (Highest Common Factor) of the given numbers.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Here, we will be using the prime factorization method.

Prime factorization of the given numbers :

261 = 3×3×29

639 = 3×3×71

816 = 2×2×2×2×3×17

Common factor(s) in the above mentioned prime factorizations = 3

So, HCF = 3

(This will be considered as the final result.)

Hence, the HCF of the given numbers is 3
