Why do you only need to look at the last two digits of a number to know if it is divisible by 4?
If a number is divisible by 4, the last two digits are divisible by 4. For example, the number 314 is not divisible by 4, but 316 is divisible by 4, because 16 is divisible by 4.
How do you know if a number is divisible by four?
Whole numbers are divisible by 4 if the number formed by the last two individual digits is evenly divisible by 4. For example, the number formed by the last two digits of the number 2628 is 28, which is evenly divisible by 4 so the number 2628 is evenly divisible by 4.
How can you tell if a number is divisible by 4?
A number is divisible by 4 if the last two digits form a number that is divisible by 4, for example 612 is divisible by 4 (because 12 is divisible by 4).
How is 416 divisible by 4?
416 divided by 4 equals 104, a whole number. Since there is no remainder, we know that 416 is divisible by 4.
How do you tell at a glance that a number is divisible by 4?
A number is divisible by 4 if the last two digits form a number that is divisible by 4, e.g. 312 is divisible by 4 (because 12 is divisible by 4).
