Because a pair of numbers is a pair of numbers.
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.
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.
Factors are numbers you can multiply together to get another number. The factor pairs are: (1, 52) (2, 26) (4, 13)
The prime factors of 24 are 2 and 3
All numbers have factors. It is possible to list them as pairs. The factors of 12 are 1, 2, 3, 4, 6 and 12. The factor pairs of 12 are (12,1)(6,2)(4,3)
its numbers that are extend examples:12:2*6,3*4,1*12,
The factor pairs of 98 are :- 1 x 98 2 x 49 7 x 14 The pairing that total 51 are 2 and 49.
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.
A factor pair is two numbers. A factor pair is the set of two factors that when multiplied together result in the number of which they are factors. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. The factor pairs are 1 x 12, 2 x 6, and 3 x 4.
Try to factor this number. Look for small factors first - numbers like 2, 3, 5, 7. That is, try whether your number is divisible by such numbers. Once you find such a factor, divide the number by your factor to get the other factor.
