The LCM of two numbers is 225 and their HCF is 5. If one number is 25, the other number is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 45
For any two numbers, HCF \(\times\) LCM \(=\) product of the numbers.
\(25\times\text{other}=5\times225=1125\)
Other number \(\displaystyle =\frac{1125}{25}=45\)
HCF of 25 and 45 is 5 and their LCM is 225, as given
The other number is 45.
