Question

Find the HCF of the following using the prime factorisation method 36 180 1260

Answer 1

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 1269=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

1269=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 common 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.

hope it helps
