If it ends with an even number then it is divisible by 2

Being divisible by 4, means that it will also be divisible by 2, so that doesn't tell you anything about divisibility by 8. But if you divide the number by 2, and this quotient is divisible by 4, then yes the original number is divisible by 8.

To determine if a number is even or odd, you can check if the number is divisible by 2. If the number is divisible by 2 without leaving a remainder, then it is even. If the number is not divisible by 2 or leaves a remainder when divided by 2, then it is odd.

A prime number is one that has only two factors: one and itself.You can tell if a number is prime quickly by using the Laws of Divisibility:Numbers that end in 0, 2, 4, 6, and 8 are divisible by 2.If the sum of a number's digit is divisible by 3, the number itself is divisible by 3.If the last two digits of a number are divisible by 4, the number itself is divisible by 4.If a number ends in 0 or 5, it is divisible by 5.If a number is divisible by both 2 and 3, it is divisible by 6.If you double the last digit and subtract it from the rest of the number and the answer is 0 or divisible by 7, it is divisible by 7. For example, 4364: 4 doubled is 8. 436 - 8 = 424. You still cannot readily tell if the number is divisible by 7, so you can do it again: 4 doubled is 8. 42 - 8 = 34. 34 is not divisible by 7 so 436 is not divisible by 7If the last three digits of a number are divisible by 8, the number itself is divisible by 8.If the sum of the digits of a number is divisible by 9, the number itself is divisible by 9.If a number ends with 0, it is divisible by 10.If you add every other digit and then subtract the rest of the digits and the answer is 0 or is divisible by 11, the number itself is divisible by 11. For example: 1364: 1+ 6 = 7 and 7 - 3 - 4 = 0. The number is divisible by 11.If the number is divisible by 3 and 4, it is divisible by 12.There are more divisibility rules that can be used for large numbers.

It is divisible by 2 such that the quotient is a whole number.

No. 319 is not divisible by 2. An easy way to tell If a number is divisible by 2 is that it will end with an even number (eg. 2, 4, 6, 8.. etc).

Being divisible by 4, means that it will also be divisible by 2, so that doesn't tell you anything about divisibility by 8. But if you divide the number by 2, and this quotient is divisible by 4, then yes the original number is divisible by 8.

If the number is divisible by 2 and 3, it can also be divided by 6.For example - 12126 is divisible by 2 and 3 and6Divide it by 6 and see if you get a whole number.

To determine if a number is even or odd, you can check if the number is divisible by 2. If the number is divisible by 2 without leaving a remainder, then it is even. If the number is not divisible by 2 or leaves a remainder when divided by 2, then it is odd.

Because 8 is 2 cubed, you can test if a number is divisible by 8 by dividing it by 2 three times. If the number you reach is an integer, then the number is divisible by 8. For example, 72/2 = 36/2 = 18/2 = 9. Therefore, 72 is divisible by 8. For very large numbers, if the last three digits are divisible by 8, the number itself is divisible by 8.

You can tell if the last 2 digits of the number can be divisible by 4 or 8. So the number 3156372856374856386578365864would be divisible by 8 because 8 can go into 64.

It is divisible by 2 such that the quotient is a whole number.

no because 969 is an odd number and 2 is an even number, also you can tell if you divide 969 by two your answer is a decimal point (484.5) and in order for it to be divisible by 2 it can not be a decimal it has to be a whole number..
