The HCF and LCM of two numbers are 13 and 1989, respectively. If one of the numbers is 117, then determine the other

Correct Answer: 221

Explanation:

Given,
LCM = 1989, HCF = 13
1st number = 117 and
2nd number = ?
According to the formula,
Product of LCM and HCF = Product of two numbers
∴ 1989 x 13 = 117 x ?
? = (1989 x 13)/117
? = 221
