Question

Using divisibility test, determine $14560$ is divisible by $4$and $8$.

Answer 1

Step 1 : Checking the divisibility by $4$

If the last two digits of a whole number are divisible by $4$ , then the entire number is divisible by $4$.

When $60÷4=15$, we get remainder zero, so $14560$ is divisible by $4$.

Step 2 : Checking the divisibility by $8$

If the last three digits of a whole number are divisible by $8$ , then the entire number is divisible by $8$.

When $560÷8=70$,we get remainder zero, so $14560$ is divisible by $8$.

Hence, $14560$ is divisible by $4$and $8$.
