Question

Find the Hcf of a)6 and 36 b)17 and 85

Answer 1

Answer:

hcf of 6and 36 is 6

hcf of 17 and 85 is 17

plz mark me brainliest

Answer 2

Explanation:

(a)By Euclid's division Lemma,

a = bq + r ( 0<r<b)

a = 36 & b = 6

36=6*6 + 0

So, the HCF of 6 and 36 is 6.

U can also perform prime factorisation method to find out HCF 6 and 36.

(b) By Euclid's division Lemma,

a = bq + r ( 0<r<b)

a = 85 & b = 17

85 = 17*5 + 0

So, the HCF of 17 and 85 is 17

U can also perform prime factorisation method to find out HCF 17 and 85.
