​

Answer 1

Answer:

you can find it by prime factorisation method

Answer 2

$\huge \mathfrak \green{answer}$

Let the LCM be x

The HCF is 45×x=45x

Sum of LCM and HCF x+45x=115046x=1150x= 46

1150x=25

So LCM is 25 and HCF is 45×25=1125

Let a,b be two numbers

We know that ab=LCM×HCF

225×b=25×1125

b= 22528125

b=125

So the other number is 125
