Question

findthe highest number which divides 27 and 45 respectively

Answer 1

Answer :

To find the highest number which divides 27 and 45 , We find HCF of 27 and 45

First we make prime factors :

27 = 3 $\times$ 3 $\times$ 3
And
45 = 3 $\times$ 3 $\times$ 5

So,

HCF ( 27 , 45 ) = 3 $\times$ 3 = 9

Then

The highest number which divides 27 and 45 = 9 ( Ans )
