Question

find the hcf and LCM 161 and 207​

Answer 1

Step-by-step explanation:

To get the Least Common Multiple (LCM) of 161 and 207 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:

161: 723207: 33 23LCM: 33723

The Least Common Multiple (LCM) is: 3 x 3 x 7 x 23 = 1449

pls follow me

Answer 2

161= 7×23

207 = 3×3×23

HCF = highest common factor

= 23

LCM = common×other factors

= 23×7×3×3

= 1449 Ans.
