Answer 1

252 = 2*2*3*3*7
Hence it should be divided by 7 to be a perfect square
252/7 = 36
Root of 36=6

2925 = 3*3*5*5*13
Hence it should be divided by 13
2925/13 = 225
Root of 225= 15

396 = 2*2*3*3*11
Hence it should be divided by 11
396/11 = 36
Root of 36 = 6

2645= 5*23*23
Hence it should be divided by 5
2645/5= 529
Root of 529 = 23

1620 = 2*2*3*3*3*3*5
Hence it should be divided by 5
1620/5 = 324
