Question

Find the HCF of the following using the Prime factorisation method.
36, 180, 1260

Answer 1

Answer:

HCF Of 36, 180, 1260 is 36.

Step-by-step explanation:

First Step:-

Take the factors of 36=2*2*3*3

Second Step:-

Take the factors of 180=2*2*3*3*5

Third Step:-

Take the factors of 1260=2*2*3*3*5*7

Fourth Step:-

Take the all three numbers factors

36=2*2*3*3

180=2*2*3*3*5

1260=2*2*3*3*5*7

Next step see the common no. in all three numbers factors that is 2*2*3*3.

You see that 2*2*3*3 are comman in all three numbers factors that is 36, 180 and 1260.

and next step is multiply all the common factors that is 2*2*3*3 = 4*9 = 36.

So the HCF is 36.
