Factors are those numbers which that can completely divide the number. You can observe that, factors have a great impact on mathematical problem-solving starting from lower grades. We use factors in getting ingredients for cooking or for assorting gifts.
As it is a prime number, there 13 has only 2 factors — 1 and 13.
Children find factors in solving. While doing the calculations, most times, students forget to take 1 and the number as factors. Few methods are explained below for easy solution of factors -
The multiplication method finds the pair of factors that give 13 as their product.
Multiply the factors 1 and 13, 1×13 = 13.
The division method finds the numbers that perfectly divides the given number 13.
1 and 13 are the only factors that the number 13 has. So to verify the factors of 13 using the division method, we just need to divide 13 by 1→ 13/1 =13 and 13 by 13→ 13/13 =1
To get the 13 as their product, we multiply a set of prime numbers, and that set is called prime factors. Prime factorization is the process of breaking down the number into its prime factors.
Factor tree: A factor tree is not necessary to find the factors of 13. Since 13 is a prime number, the multiplication and division methods are enough to calculate the factors of 13. Factor trees are useful when you are dealing with composite numbers.
Factor Pairs - Factors of 13 can be written in both positive pairs and negative pairs.
Positive pair : (1,13)
Negative Pair: (-1,-13)
The product of the factor pairs will be equal to the number 13. 1×13=13 and -1×(-13)=13.
