Answer 2

Step-by-step explanation:

First let's find the lcm of the given numbers

3| 9, 21, 25, 45

5| 3, 7 , 25, 15

3| 3, 7, 5, 3

1, 7 , 5, 3

we have ,

3³×5²×7 = 27×25×7= 4725

and now we need a number which when added with 5

becomes our new lcm

lets say,

x+5 = 4725

therefore x = 4725-5= 4720
