Donna must choose a number between 61 and 107 that is a multiple of 2 , 4 , and 5 . Write all the numbers that she could choose. If there is more than one number, separate them with commas.
The lowest common multiple of 2, 4 and 5 is 20, so the required numbers must be divisible by 20.
I'm sure you can now work out which ones they are.
