Question

What's the hcf of 540,980

Answer 1

Answer:

Step-by-step explanation:we will find hcf of 540 and 980 by euclids division lemma

980=540×1+440

540=440×1+100

440=100×4+40

100=40×2+20

40=20×2+0

so the hcf obtained is 20

Answer 2

V 540 = 2x2x3x3x3x5
980 = 2x2x5x7x7
So HCF = 2x2x5
= 20
