Question

HCF (a) 161,325 (b)345,506

Answer 1

Hey Mate,

Highest Common Factor : The largest common factor that can divide the given numbers without leaving any remainder.

a) 161, 325

161 = 23 x 7

325 = 13 x 5 x 5

Since, there is no common factor besides 1, the HCF of 161 and 325 is 1.

b) 345, 506

345 = 23 x 5 x 3

506 = 23 x 11

Since, the only common factor besides 1 is 23, the HCF of 345 and 506 is 23.

Hope it Helps!
