Question

The HCF and LCM of two numbers are 13 and 1989 respectively if one of the number is 117 find the other

Answer 1

product of numbers =LCM ×HCF
let other number be x
117×x =13×1989
x=13×1989/117
x=1989/9
x=221 is other number

Answer 2

Question:

The HCF and LCM of two numbers are 13 and 1989 respectively. If one number is 117 find the other.

Answer:

• Other Number = 221

Solution:

Given:

• HCF = 13
• LCM = 1989
• One Number = 117

To Find:

• Other Number = ?

We Know that,

• $Other \: Number = \frac{HCF \times LCM}{one \: number}$

$= \frac{13 \times 1989}{117}$

$= \frac{25857}{117}$

$= 221$
