What number is the greatest common factors of a number under 50?
If we are trying to find the two numbers less than 50 with the greatest common factor, we need to pick two numbers with a larger difference between them, since the greatest common factor between two numbers cannot be greatest than the difference between the two numbers. To create a large difference, we will want one number to be close in value to 50. And, for the greatest common factor, we want the other number itself to be the greatest common factor. The greatest common factor that the larger number can have (since it is larger and thus cannot be the greatest common factor itself) is the number which is half its value. So, if we choose the even number closest in value to 50, we get 48. Then, if we take half of it, we get 24. The greatest common factor of 24 and 48 is 24. This is the largest possible greatest common factor of a pair of numbers less than 50.
Which prime number is not an odd number?
2 is the only prime even number, as prime numbers go into itself and 1. Even numbers tend to have, at the very least, 1 times itself and 2 times one-half of itself.
What is the second greatest factor of any number and how does this relate to the greastest factor of any number?
The greatest factor of any number is the number itself. The second greatest factor of any even number is half the number. The second greatest factor of any composite number is the number divided by its smallest prime factor. The second greatest factor of any prime number is 1.
What is 10.5 as a whole number?
10 and a half, being between the whole numbers 10 and 11, can't be a whole number itself.
What is a number divisible by 4 but not by 2?
There are none. As a factor of 4, 2 is a factor of all numbers that are multiples of 4. The reverse comparison is true, however, because only half (exactly half) of the numbers divisible by 2 are also divisible by 4.
Why do all even numbers have 2 as a factor?
All even numbers have 2 as a factor because they are all divisible by 2. Half of the numbers are odd and half of them are even. It makes sense that half of them would be divisible by 2.Because of the definition of an even number (an even number is an integer that can be divided by 2 evenly; with no remainer).
Is the only factor greater than half itself?
That's true.
Is it true that the only factor greater than half is itself?
Yes.
When do factors pairs reverse order?
Factor pairs reverse once you have gone through the number that is half the number it started with. For instance, 12 divided by to is 6, so once you reach 6 in you factor pairs, the numbers will reverse. With an odd number such as 7, the center point would be 3 and 4. Even though these numbers aren't like 12, where it is 6 and 6, this is 7 divided by 2 without decimals, instead a lower half and upper half. At that point, the factor pairs reverse.
What is the factor of 19?
19 is a prime number. Half of 19 is 9.5 and, 4 5, 3, 6, 7, 8 don't go into it. A prime number has to gave a perfect factor other than itself and 1.
What is the median number of 11.5 and 22.5?
It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.It is the number halfway between them or half of the total of the two numbers, so 17 is the median.
