Question

find the hcf of 8 18 20 with method​

Answer 1

Answer:

2

Step-by-step explanation:

8 = 2×2×2

18 = 2×3×3

20 = 2×2×5

2 is common from these.

so hcf is 2.

Answer 2

Answer:

HCF of 8,18 and 20 is 2

Step-by-step explanation:

8,18and20

$a = bq + r$

let a be 20 (the highest value) and b be 18

20=18*1+2. (18 multiple by 1 is 18 and on adding 2 in it becomes 20

then the divisor(b) brcomes the dividend (a) and remainder becomes 2

18=2*9+0(since remainder is 0 so the divisor will become the hcf if 18 and 20)

now 8 is left (the hcf of the above no. would bevome the divisor for the 3rd no.)

8=2*4+0

therefore the hcf of 8,18 and 20 is 2
