WebSolution : We know that if the given number is divisible by both 3 and 5, then it is divisible by 15. First, check whether the given number is divisible by 3. Sum of the digits : 4 + 1 + 2 + 9 + 5 = 21. Sum of the digits (21) is a multiple of 3. So, the given number is divisible by 3. Now, check whether the given number is divisible by 5. hotels near wrightsboro rd augusta gaWebDivisibility and factors. A number is considered divisible by another number ( divisibility) when the result of the division is an integer and there is no remainder.

If a and b are integers such that a ≠ 0, then we say " a divides b " if there exists an integer k such that b = ka. If a divides b, we also say " a is a factor of b " or " b is a multiple of a " and we write a ∣ b. If a doesn’t divide b, we write a ∤ b. For example 2 ∣ 4 and 7 ∣ 63, while 5 ∤ 26. lim proof pant womenWebA divisibility rule is a heuristic for determining whether a positive integer can be evenly divided by another (i.e. there is no remainder left over).
