Answer:
Other number is 153
Explanation:
Usually, the product of the HCF and LCM will be the product of the 2 numbers in question.
The HCF and LCM are given as 9 and 459.
While one of the numbers used to find the HCF & LCM was 27.
Let the other number be y.
Thus;
27y = 459 × 9
y = 459 × 9/27
y = 153
