We can write 15 as (5×3) so if a number is divisible by 5 and 3 then the number is divisible by 15. Example: 75 / 15= 5 because 75 is divisible by 5 and 3 .so the number is divisible by 15. Example: 35445 / 15= 2363 because 75 is divisible by 5 and 3 .so the number is divisible by 15. Example: 756555 / 15= 50437 because 75 is divisible by 5 and 3 .so the number is divisible by 15. Example: 2034645 / 15= 135643 because 75 is divisible by 5 and 3 .so the number is divisible by 15. Example: 59985465 / 15= 3999031because 75 is divisible by 5 and 3 .so the number is divisible by 15. Note: So Before going to divisible by 15 any number, first check the condition of a number isdivisible by 5 and 3 is possible than divisible by 15 is possible. Than numbers is divisible by 15.
