Detailed Solution

Given that a number is 725, and with another number, the HCF is 145 and the LCM is 2175.
We know that,
HCF × LCM = Product of the numbers.
Let us assume the other number to be x.
Then we have,
725×x=145×2175 x= 145×2175 725 x=145×3 x=435
So, the other number is found to be 435.
Hence, the correct option is (2).
