What Are the Factors of 7?
Let us recall, "What is a factor?" A factor is a number that divides another number equally without leaving a remainder.
Factors of 7 are 1 and 7.
The number 7 has only two factors, and hence it is a prime number.
How to Calculate the Factors of 7?
Factors of 7 can be calculated by the division method and the prime factorization method.
To find factors of 7, we start dividing 7 with 1.
 7 /1 = 7
 7 × 1 = 7
As 7 is an odd number, all of its factors will also be odd.
7 is divisible by 7.
Hence, the factors of 7 are 1 and 7.

Factors of 7 by Prime Factorization
Prime factorization is a process of breaking down a composite number into its prime factors.
To get the prime factorization of 7, we divide it by its smallest prime factor, which is 7.
7/7 = 1
The process goes on till we get quotient 1.
It can also be represented in a factor tree.
Factors of 7 in Pairs
The pair of numbers which gives 7 when multiplied is called the pair factor of 7. Factors of 7 are 1 and 7.
Since there are only two factors, we have only one pair.
Factors of 7 in pair is (1, 7).
Negative integers can also be the factors of 7.
The negative pair factors of 7 are (1, 7).
Important Notes:
 A factor is a number that divides another number equally without leaving a remainder.
 Negative integers such as 1 and 7 can also be the factors of a number since their product gives a positive integer 7.

The positive pair factors of 7 are, (1, 7), (7, 1).
Hence, there are 2 positive pair factors of 7.

Example 3: Find the Least Common Multiple and Greatest Common Divisor (GCD) of 7 and 7.
Solution:
The factors of 7 are 1, 7, and factors of 7 are 1, 7.
Therefore, the Least Common Multiple of 7 and 7 is 7 and the Greatest Common Divisor (GCD) of 7 and 7 is 7.
FAQs on Factors of 7
What are the Factors of 7?
The factors of 7 are 1, 7 and its negative factors are 1, 7.
What is the Greatest Common Factor of 7 and 5?
The factors of 7 are 1, 7 and the factors of 5 are 1, 5. 7 and 5 have only one common factor which is 1. This implies that 7 and 5 are coprime.
Hence, the Greatest Common Factor (GCF) of 7 and 5 is 1.
What Numbers are the Prime Factors of 7?
The prime factor of 7 is 7.
What is the Sum of all the Factors of 7?
Since all factors of 7 are 1, 7 therefore, the sum of its factors is 1 + 7 = 8.
How Many Factors of 7 are also Factors of 4?
Since the factors of 7 are 1, 7, and factors of 4 are 1, 2, 4. Hence, 7 and 4 have only one common factor which is 1. Therefore, 7 and 4 are coprime.
