Do you know how number tricks work? Most of the number tricks work because of the unique characteristics of each number, i.e., factors. A factor of a number is any number that can evenly divide the number. For distributing objects, we use factors in our daily life.
The numbers which can evenly divide 2 are the factors of 2. 1 and 2 are the factors of 2.
Negative factors of 2: The negative factors of 2 are the negative counterparts of the positive factors. -1 and -2 are the negative factors of 2.
Prime factors of 2: A prime number is a number which has only two factors, i.e., 1 and the number itself.
2 is the only prime factors of 2 as 2 is a prime number.
Prime factorization of 2: The process of splitting a number into smaller prime numbers is prime factorization. Here, the product of prime numbers is the number itself.
The prime factorization of 2 is 21
Factors of a number is a number which can evenly divide the number. Some methods which are used to find the factor of a 2 are,
In the multiplication method a pair of numbers are identified, the product of multiplying the number is 2.
Step 1: Find the numbers whose product is 2.
1 × 2 = 2
Step 2: List them as pairs
The pair of factors are (1, 2).
In the division method, we need to check which number can evenly divide 2.
Let’s check the factors of 2 using division method
2 ÷ 1 = 2
So, the factors are 1 and 2.
Prime numbers are the numbers which have only two factors. The process of breaking down a large number into a smaller prime number is prime factorization.
To find the factors of a number prime factorization, we need to follow these steps
Step 1: The given number needs to be divided with the smallest prime number.
Step 2: Now, we need to divide the remainder in step 1 with the prime number. The process is continued till the remainder is a prime number.
Prime factorization of 2 is 21
The Pictorial representation of factors of a number. It is in the form of a tree where the given number is split into branches which represent all the factors.
The factor tree of 2:
A pair of factors of a number. The product of those numbers is the number itself. Factor pairs can be both positive and negative.
Positive pair factors: (1, 2).
Negative pair factors: (-1, -2).
