I have a Divide and Answer maths question. Struggling with this though I have tried long and hard. I have five numbers 152 95 209 114 38 228 . They can all be divided by one number greater than 1 WITHOUT leaving a remainder. Please can you clever people help? I would appreciate it.

1 to 4 of 4

Dont think I asked that question correctly. I have to replace in the empty central box a number by which all the other numbers can be divided without leaving a remainder. The number is greater than one.
19
!9
The way to do this is to take the smallest number first and split that into its factors. These are 2 and 19. Both are prime numbers.

You then notice that other numbers are odd (95 and 209). These cannot be divided by 2

Therefore the only possible solution is 19
Check
152/19 = 8
95/19 = 5
209 /19 = 11
114 /19 = 6
228/19 = 12
