Question

find the HCF of 18a³ and 27a²b​

Answer 1

Given: $18a^{3} \ and\ 27a^{2} b$

We have to find the HCF of the above numbers.

As we know that the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

We are solving in the following way:

We have,

$18a^{3} \ and\ 27a^{2} b$

The factors of $18a^{3}$ are: $1, 2, 3, 6, 9, 18,a,a,a$

The factors of $27a^{2} b$ are: $1, 3, 9, 27,a,a,b$

Then the greatest common factor is$9\times a$.

Hence, the HCF of the above numbers is$9,a\ or\ 9a$.
