Question

HCF of 540,420 and 480

Answer 1

Answer:

I dont know how to find hcf for 3 numbers but by using Euclids Theorem We can find for 2 numbers with the formula a=bq+c

HCF of 540,420

540 = 420 * 1 + 120

420 = 120 * 3 + 60

120 = 60 * 2 + 0

So 60 will be HCF for 540 and 420

In the same way you do for 420,480 and 540,480 you will get 60 as HCF
