Factor pairs are two numbers multiplied together to get one number. Examples: One factor pair of 24 is 4, 6. One factor pair of 70 is 5, 14. One factor pair of 144 is 12, 12.
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
An infinite number of number pairs have a greatest common factor of 850. One example is 1700 and 2550.
The factor pairs of 29 are 1 and 29. 29 is prime so it has only one factor pair.
36, for one.
Prime numbers have one factor pair. Composite numbers have two or more pairs. (6,8) and (4,12) are two different factor pairs for 48.
Prime numbers have one factor pair.
Factor pairs are two numbers multiplied together to get one number. Examples: One factor pair of 24 is 4, 6. One factor pair of 70 is 5, 14. One factor pair of 144 is 12, 12.
In that case, one of the numbers is a multiple of the other.
They are called relative prime numbers.
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.
Because a pair of numbers is a pair of numbers.
Only two: (4, 9) and (6, 6). In all other factor pairs, one of the numbers is not composite.
3 and 6 4 and 8
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
17 has one factor pair, 1 and 17.
To distinguish them from prime numbers. Composite means "made up of various parts or elements." Prime numbers have one and only one factor pair. Composite numbers have a various number of factor pairs, but always more than one.
