How can you tell that 9472 is divisible by 8?
The last three digits are divisible by 8.
Is it true that a number is divisible by 8 if it divisible by 4 and 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.
How do you tell if a number is divisible by 8?
If the last three digits can be divided evenly by 8, then so can the entire number
How do you tell if a number is prime or not?
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.
What is a number that divisible by 2 and also divisible by 8?
no.. for example 6,12,18 are divisible by 2..but not divisible by 8.
How can you tell that 9472 is divisible by 8?
The last three digits are divisible by 8.
How can you tell if a number can be exactly divided by eight?
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.
Is it true that a number is divisible by 8 if it divisible by 4 and 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.
How can you tell without dividing by 8 that 376 is exactly divisible by 8?
If you can cut it in half three times and get a whole number each time, it's divisible by 8.
How do you tell if a number is divisible by 8?
If the last three digits can be divided evenly by 8, then so can the entire number
You can tell if a is divisible by 2 if the ends with what?
If it ends with 0, 2, 4, 6 or 8.
Is 319 divisible by 2?
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).
When is a number divisible by 8?
If the last 3 digits are divisible by 8, the number is divisible by 8.
