Divisibility Rules Practice Problems A 5 digit number divisible by 3is to be formed using the numerals 0,1,2,3,4 and 5 without repetition the total number of ways this can be done is.a 5 digit n. The divisibility rule for 3 can be understood with the help of the following examples. example: test the divisibility of the following numbers by 3. a.) 1377. b.) 2130. c.) 3194. solution: a) in 1377, the sum of all the digits = 1 3 7 7 = 18. since 18 is divisible by 3, it means 1377 is also divisible by 3. Our divisibility test calculator has two modes: details and summary. in the summary mode, you can overview the divisibility properties of a given integer: the calculator will tell you which numbers between 2 and 13 are its divisors. in the details mode, you can understand why a number between 2 and 13 is (or is not) a divisor of a given integer. Examine some three digit numbers 124 is the same as 100 24, and we know that 100 is divisible by 4 so all that matters here is whether or not 24, or the last two digits, are divisible by 4. the same could be said for any three digit number 224 = 200 24, and we know that 200 is divisible by 4 so again all that we're worried about are these last two digits.
