you divide the number, say the number was 350 and you were seeing if 3 was a factor of it, you would input 350 divided by three and the answer would be 116.666666... so no 350 is not divisible by 3 basically you have to divide it on a calculator and to be divisible it has to be a whole number. hope it helps.
