Question

find the hcf and lcm of 117 and 221

Answer 1

117 = 3² × 13

221= 13 × 17

HCF = 13

LCM = 3²×13×17=1989

Answer 2

Answer:

HCF and LCM of 117 and 221 are 13 and 1989 respectively

Step-by-step explanation:

Given the two numbers 117 and 221

we have to find the LCM and HCF

Factors are

$117=3\times 3\times 13$

$221=13\times 17$

HCF and LCM is

$HCF(117,221)=13$

$LCM(117,221)=3\times 3\times 13\times 17=1989$

HCF and LCM of 117 and 221 are 13 and 1989 respectively
