Question

find the hcf of 45 75 and165

Answer 1

Answer: 15

Step-by-step explanation: First we find HCF of 45 and 75.

let a=75 and b=45

a=bq+r

75= 45 x 1 + 30

a=45 and b=30

45= 30 x 1 + 15

a=30 and b=15

30= 15 x 2 + 0

therefore, HCF of 45 and 75 is 15

Similarly for 165, we divide 165 by 15.
