Question: 1 / 400

What rule should Mrs. White's students apply to determine the divisibility of 256 by 4?

If the last two digits are divisible by 2

If the last two digits are divisible by 4

The correct choice is based on the divisibility rule for the number 4. A number is considered divisible by 4 if the number formed by its last two digits is divisible by 4. In the case of 256, the last two digits are '56.' When you check if 56 is divisible by 4, you indeed find that it is (56 divided by 4 equals 14).

This rule applies specifically to 4, differentiating it from the criteria used for other numbers. For instance, the rule regarding being divisible by 2 involves only the last digit, and while an even total for the digits suggests divisibility by 2, it does not apply for divisibility by 4. Each of the alternative options reflects less specific criteria related to number 4, making the understanding of these rules essential for accurately determining divisibility.
