Applying Divisibility Tests to $5{,}625$

To check which common factors divide $5{,}625$ , we evaluate it against standard divisibility tests line by line:

By $2$ : It is not divisible by $2$ because the final digit ( $5$ ) is not an even number.
By $3$ : It is divisible by $3$ because the sum of its digits ( $5 + 6 + 2 + 5 = 18$ ) is evenly divisible by $3$ .
By $5$ : It is divisible by $5$ because its final digit is $5$ .
By $6$ : It is not divisible by $6$ ; a number must be divisible by both $2$ and $3$ to meet this rule, and $5{,}625$ fails the test for $2$ .
By $10$ : It is not divisible by $10$ because it does not end in $0$ .
