Question

The LCM of two number is 126 and their Hcf is 6 .if one of two number is 18 what 8s the other number

Answer 1

Answer:

The other number is 42

Step-by-step explanation:

Given one number is 18

let the other number be X

LCM * HCF = Product of two numbers

126 * 6 = 18 * X

756 = 18* X

X = 756/18

X = 42

Answer 2

Answer:

56

Step-by-step explanation:

Given :

• LCM = 126
• HCF = 6
• 1st number = 18
• Other number = ?

We know that :

$2nd \: number \: = \frac{hcf \times lcm}{1st\: number \: }$

$= \: \frac{126 \times 6} { 18}$

$= 56 \:$
