Yes. If the sum of a number's digits add up to 3 (or a multiple of 3) then the number is divisible by 3. 5 + 3 + 1 = 9 : as 9 is a multiple of 3 then 531 is divisible by 3 (177 x 3 = 531). NOTE : A similar process applies to identify if a number is divisible by 9. If the sum of the number's digits add up to 9 (or a multiple of 9) then the number is divisible by 9. 5 + 3 + 1 = 9 : 531 = 59 x 9.
531 is not a prime number. Other than itself and one, it is also divisible by 3, 9, 59, and 177.
531 is one of them and that any 3 digit number whose digital sum is 9 is also divisible by 9
1 x 531 = 531 3 x 177 = 531 9 x 59 = 531
It is: 531/2 = 265.5
