What is the difference between factor pairs and distinct factor pairs?
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.
Can you stop checking for factor pairs when you find a pair that repeats?
No, you should continue checking for factor pairs even if you find a pair that repeats. A repeating pair indicates that the number is not a prime number, but there may be other factor pairs that have not been identified yet. It is important to exhaust all possible factor pairs to ensure that all factors of the number are identified accurately.

How solve factorization?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
What is a number called that has an odd number of factor pairs?
A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
What is the difference between factor pairs and distinct factor pairs?
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.
How do you find factor pairs of a number?
Factor pairs are just the factors of a number listed in a different way. The factors of 20 are 1, 2, 4, 5, 10, 20 The factor pairs of 20 are (20,1)(10,2)(5,4)
How many factor pairs does 21 have?
The factor pairs of 21 are:1, 213, 7Therefore, the number 21 has two pairs of positive integer factors.
What number has 6 factors pair?
60 has 6 factor pairs.
Why does a square number always have an odd number of factors?
Factors can be listed as factor pairs. With square numbers, one of those pairs will be the same number twice. When written as a list, only one of them will be used, leaving an odd number of factors.
If you know a factor of a number can you find another factor explain?
Factors come in pairs. If you know one factor, divide it into the number. The answer will be another factor.
What does the word factor pairs mean?
For every factor of a number, there is another factor that results when you divide the first factor into the number. Factors can be listed in pairs. Since 9 x 4 = 36, (9,4) is a factor pair of 36.
What are the factors and factor pairs of 13?
1 and 13. It is a prime number, so those are its only factor.
How would a list of factors pairs relate to the rectangles that could be made to show the number?
As I understand it, the number of factor pairs is equal to the number of rectangles.
How many pairs of factors does number 4 have?
The number 4 has two factor pairs. 1 x 4 and 2 x 2
What are all the factor pairs of 52?
