Answer 2

Given:

I am a number twice the HCF of 240,300, 450.

To Find:

Who am I? 1) 60 2) 50 3) 40 4) 80​

Solution:

HCF or Highest Common Factor of two numbers is the highest number that is a factor of the two numbers which can divide the two numbers evenly.

To find the HCF of the given numbers we will use the factorization method, we will factorize each number,

240=2*2*2*2*3*5

300=2*2*3*5*5

450=2*3*3*5*5

So the HCF will be the multiplication of the common factors among the three that is,

HCF=2*3*5

      =30

So the number will be twice the HCF that is 2*30=60

Hence, the correct option is (1)60.
