Question

the HCF and LCM of two numbers are 6 and 840 respectively if one of the number is 42 find the other number​

Answer 1

we know that

HCF × LCM = PRODUCT OF TWO NUMBERS

840×6=42×A

A is other number

=> A=840×6/42=120

hope you get this

Answer 2

The other number is 120

Step-by-step explanation:

Hcf of two numbers = 6

LCM of two numbers = 840

One of the number = 42

let the second number be x

Formula :$HCF \times LCM = \text{Product of two numbers}$

$6 \times 840 = 42 \times x$

$\frac{6 \times 840}{42}= x$

120 = x

Hence The other number is 120
