Divisible, meaning you can divide the said sum by 3 and not get any remainder from the division process Any number multiplied to 4 also gives an even number as its product Any number multiplied to 5 gives a product with its ones digit ending in 0 if it is multiplied to an even number, or 5 if multiplied to an odd number The multiples of 6 are even numbers and the sum of their digits are divisible by 3 Numbers multiplied to 10 will always have products ending in zero.
