Work your way through the prime number posibilities. It's odd so there are no even factors. Add all the digits together (to get 12) and the result has a factor of 3 so 561 has a factor 3. Divide by that factor 3 to get 187. Try again for another factor 3 and there isn't one. The number 187 doesn't end in 5 (or 0) so 5 is not a factor. 7 doesn't divide exactly. 9 doesn't divide exactly. 11 does, so it is a factor. Divide by 11 to get 17 which is a prime number, so that's the finish. The factorization is 3x11x17
divide it by the denominator. which would be three.
how to divide 3 into 75
Take a inch and divide it into 3parts
For a number to be divisible by 3, its digit sum has to be divisible by 3. For a number not to be divisible by 2, the last digit must be a 1,3,5,7 or 9. Using these rules, the numbers between 500 and 600 that divide by 3 but not 2 become clear: 501, 507, 513, 519, 525, 531, 537, 543, 549, 555, 561, 567, 573, 579, 585, 591 and 597
The factors of 561 are 1, 3, 11, 17, 33, 51, 187, and 561.
