What number is divisible by 8 and also divisible by 4?
All numbers in the 8x table. 8, 16, 24, 32, 40, 48, 56, 64... etc.
How do you know a number is divisible by 4?
If a number can be divisible by 2 twice( ei, 48 in half is 24 and 24 can be divided in half. But you can check, without doing any dividing. If the last 2 digits (the tens and ones place digits) is divisible by 4, then the whole number is divisible by 4. How to tell if the last two digits are divisible by 4: add the ones digit to twice the tens digit: if this sum is divisible by 4, then so is the original. This sum can be repeated until a single digit remains. IF this digit is 4 or 8, then the original number is divisible by 4. So if you have a number 975239806723498658859303524, then the last two digits are 24, which is divisible by 4 and the entire number is divisible by 4 (4 + 2×2 = 8 which is 4 or 8, so 24 is divisible by 4). Why this works: Suppose you have a whole number M. Rewrite the number as M = 100*P + Q, where P & Q are whole numbers. Note that Q represents the last two digits, and P is the rest of the number. Now divide this by 4: M/4 = (100*P + Q)/4 = 100*P/4 + Q/4 = 25*P + Q/4. So since P is a whole number, then 25*P is a whole number, and if Q/4 is a whole number, then [M/4 = 25*P + Q/4], which is the sum of two whole numbers is also a whole number, so M is divisible by 4. Let M = 324, so P = 3, and Q = 24. 324 = 100*3 + 24, and 324/4 = 25*3 + 24/4 = 75 + 6 = 81. So 324 is divisible by 4. A number which is divisible by 4 is a multiple of 4
What number is divisible by 8?
All the numbers that are divisible by 8 are 1,2,and 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 do you know if a number is divisible by 4?
Get the last two digits of the number. If that number is divisible by 4 then that number is divisible by 4. Example : 2393844 The last two digits are 44 and since 44/4 = 11 or 44 is divisible by 4 then the number 2,393,844 is divisible by 4.
Is 1124 divisible by 4?
Yes 1124 is divisible by 4. Since 24 is divisible by 4 1124 is divisible by 4. If the last two numbers of a number are divisible by 4, the number is divisible by 4. 24 divided by 4 is 6.
Is a number divisible by 4 also a divisible by 8?
Every other number: 8, 16, 24, 32, 40... No, a number can be divisible by 4 but not divisible by 8; an example is 12.
What number are divisible by 4?
4, 8, 12, 16, 20, 24, 28, 32, 36 . . . You can tell if a number is divisible by 4 by looking at the last two numbers, for example, is 1024 divisible by 4? To solve that, look at the last two numbers, 24. Is 24 divisible by 4? Yes, because 24 is a multiple of 4, so 1024 is divisible by 4!
Why is a number that is divisible by 8 also divisible by 4?
Because 8 is divisible by 4. So of course if 8 goes into a number, 4 will too. The number 24 for example. 8 * 3 = 24 and 4 * 6 = 24. 4 is half of 8. So 4 can go into anything 8 can, but twice as many times.
How many number are divisible by 4?
4 has an infinite number of multiples, all of them divisible by 4.
How do we know that 1196 is divisible by 4?
For any number to be divisible by 4, the last two numbers have to be divisible by 4. In this instance, since the last two digits of this number are 96, and 96/4 = 24, we know that 1196 is divisible by 4.
What is smallest number that is divisible by 4 6 and 8?
24
What is the smallest number divisible by 4 6 8?
24
Is 24 a prime number?
24 is a composite number.24 is NOT a prime number.
Are all numbers divisible by both 4 and 6 also divisible by 24?
Yes.
All numbers divisible by both 4 and 15 are also divisible by what numbers?
a number is 6. All numbers divisible by both 4 and 15 are the multiples of 4 and 15. Since 4 and 15 have no prime factor in common (4 = 22, 15 = 3 · 5), then the least common multiple of 4 and 15 is equal to their product, namely 4 · 15 = 60. Every other multiple of 4 and 15 is divisible by 60. Thus, if 60 is divisible by a number then all the multiples of 4 and 15 are divisible by that number. Therefore, it is enough to check by which number in the given options is 60 divisible. Only 6 divides 60 and none of the other do. The answer must be (A).
The smallest whole number divisible by both 8 and 12 is?
The smallest whole number divisible by both 8 and 12 is 24.
