Divisibility Rules for Four

In this video, Mr. J explains the divisibility rule for the number four. He describes how to determine if a number is divisible by four by examining its last two digits. If these digits form a number divisible by four or are both zeros, then the entire number is divisible by four. Mr. J provides examples, such as 380, 6532, and 42200, to illustrate the rule. The video concludes with a quick review and a suggestion to check the description for a more detailed explanation.

What is the key step in determining if a number is divisible by four?

• Check if the number is a multiple of ten.

• Check if the last two digits form a number divisible by four.

• Check if the last digit is zero.

• Check if the number is even.

If the last two digits of a number are zeros, what can be concluded about its divisibility by four?

• The number is not divisible by four.

• The number is divisible by four.

• The number is divisible by two but not by four.

• The number is divisible by eight.

For the number 380, why is it divisible by four?

• Because it ends with a zero.

• Because the last two digits, 80, form a number divisible by four.

• Because the sum of its digits is divisible by four.

• Because 380 is an even number.

What is the result of checking the last two digits of 6532 for divisibility by four?

• The number is divisible by two but not by four.

• The number is divisible by eight.

• The number is not divisible by four.

• The number is divisible by four.
