Question

hcf of 90,135?.............

Answer 1

135=90*1+45

90=45*2+0

THEREFORE GCF is 45

Answer 2

Answer:

The HCF of the given numbers is 45.

Step-by-step explanation:

Given: The numbers are 90 and 135.

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,

The numbers are 90 and 135.

First, we will find the factors of the above numbers.

The factors of 90 are: $1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90$

The factors of 135 are:$1, 3, 5, 9, 15, 27, 45, 135$

From the above, we can see that 45 is the largest positive integer that divides each of the integers.

Then the greatest common factor is 45.

In this problem, we are assuming we have to find the HCF of the given numbers.
