3 is the smallest whole number that can be multiplied by another whole number and result in 9 (3x3) 12 (3x4) and 15 (3x5).
It doesn't give a whole number answer. 15 divided by 4 gives 3.75
The smallest number that is divisible by 20 and 15 is 60.
2.8285
I'm not sure exactly what you're looking for. The factors of 15 are 1, 3, 5 and 15. The highest number that 15 can be divided by that will result in a whole number is 15.
I assume the question means "which whole numbers give a whole number when divided by 5?" The answer is those ending in 5 or 0. Such as 10, 15, 20, 25,.... 5000, 5005, 5010,
15 or any whole number you can think of multiplied by nine and then add 6
15 is the highest number 15 can be divided by evenly.
