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.

No best answer has yet been selected by LunaLuna. Once a best answer has been selected, it will be shown here.
For more on marking an answer as the "Best Answer", please visit our FAQ.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.
Therefore your answer can only be one of these two 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
