What Are the Factors of 49?
Factors of 49 are numbers which, on dividing 49, leave no remainder. Since 49 is a composite number, it has more than two factors. Factors of 49 = 1, 7, and 49.
How to Calculate the Factors of 49?
 Starting with our idea that any number is divisible by 1 and itself, we have 49 ÷ 1 = 49 and 49 ÷ 49 = 1
 While considering numbers that can divide 49 without remainders, we start with 2 and proceed up to 24 (roughly half of 49), and check for divisibility. We find that 49 ÷ 7 = 7
 Thus we get the factors of 49 as 1, 7, and 49.

Factors of 49 by Prime Factorization
Factors of any number can be found out by the division method and factor tree method.
Division method
 Let us find the prime factors of 49 by division method. Divide the number 49 by the smallest prime number that can completely divide 49 without any remainder. 49 ÷ 7 = 7
 We cannot proceed with the division method. So, the prime factorization of 49 is 7 × 7.
Factor tree
We will do this by factor tree:
Factors of 49 in Pairs
We have only 2 positive and 2 negative factor pairs of 49. They are (1, 49) (1, 49), (7, 7) (7, 7).
Important Notes:
 There are only two pair factors of 49.
 7 is the only prime factor of 49.
Factors of 49 Solved Examples

Example 1: Rudolf wishes to find out the product of all the factors of 49. Can you help him with this problem?
Solution:
The factors of 49 = 1, 7, and 49. Therefore, the product of all the factors of 49 is = 1 × 7 × 49 = 343.

Example 2: As part of his homework, Emanuel wants to know the mean of all the factors of 49. Do you know the solution to this problem?
Solution:
Factors of 49 = 1, 7, and 49. Mean is the sum of all the terms ÷ total number of terms = (1 + 7 + 49) ÷ (3) = 19

Example 3: How many factors are there for 49?
Solution:
The factors of 49 are 1, 7, 49. Therefore, 49 has 3 factors.
FAQs on Factors of 49
What are the Factors of 49?
The factors of 49 are 1, 7, 49 and its negative factors are 1, 7, 49.
What are the Pair Factors of 49?
The pair factors of 49 are (1, 49), (7, 7).
What is the Sum of all the Factors of 49?
All the Factors of 49 are 1, 7, 49 and therefore the sum of all these factors is 1 + 7 + 49 = 57
What is the Greatest Common Factor of 49 and 37?
The factors of 49 are 1, 7, 49 and the factors of 37 are 1, 37. 49 and 37 have only one common factor which is 1. This implies that 49 and 37 are coprime.
