Question

Find the greatest number that divides each of 150, 320 and 596 completely.

• A. 4
• B. 2
• C. 6
• D. 8

Answer 1

The correct option is B

2

To find the greatest number that divides each of 150, 320 and 596 completely we will have to find the greatest common factor of these numbers ( means their HCF).

The HCF of three numbers can be found by taking any two at a time as solved below,
First, find the HCF of 150 and 320.

$\therefore$ HCF of 150 and 320 is 10.

Now, find the HCF of 10 and 596.

$\therefore$ 2 is the HCF of 10 and 596.

Hence, HCF of 150, 320 and 596 is 2.
