Question

the HCF of two numbers is 145 and their LCM is 2175 if one number is 725 find the other number

Answer 1

Hi ,

As we know HCF×LCM = Product of two numbers.

So , here one number is 725 , let the other be x.

So, According to our formula→

725x = HCF×LCM

or, x = (145×2175)/725

or, x = 315375/725

or, x = 435.

Answer → The other number is 435☺️

Answer 2

We know that,

HCF × LCM = N1 × N2

Where N1 is first number and N2 is the second number

So given, HCF = 145
LCM = 2175
N1 = 725
N2 = ?

=> 145 × 2175 = 725 × N2

=> 725 × N2 = 315375

=> N2 = 315375/725

=> N2 = 435


Hence, the second number is 435.

Hope it helps dear friend ☺️✌️
