50 is the smallest number that is the sum of two non-zero square numbers in two distinct ways: 50 = 12 + 72 = 52 + 52. It is also the sum of three squares: 50 = 32 + 42 + 52 and the sum of four squares: 50 = 62 + 32 + 22 + 12.

What Are the Factors of 50?

Factors of 50 are the numbers which on dividing 50 leave no remainder. Since 50 is a composite number, it has more than two factors. Let us find the factors of 50.We will start with 1, then move on to 2, 3,.. up to 25 (which is exactly half of 50).50 has a total of 6 factors. The factors of 50 obtained this way are 1, 2, 5, 10, 25, and 50.

DividingResult

50 ÷ 1

Gives remainder 0.

So, 1 is a factor.

50 ÷ 2

Gives remainder 0. 

So, 2 is a factor.

50 ÷ 5

Gives remainder 0.

So, 5 is a factor.

50 ÷ 10

Gives remainder 0.

So, 10 is a factor.

50 ÷ 25

Gives remainder 0.

So, 25 is a factor.

50 ÷ 50

Gives remainder 0.

So, 50 is a factor.

Prime factorization of a number refers to representing a number in the form of the products of its prime factors.

A factor tree is a special branching diagram where we find the factors step-by-step for the given number.Then we find the factors of those resulting numbers, repeating this step until we cannot factor them anymore.The ends of the branches of the factor tree give all the prime factors of the original number.

Thus, the prime factorization of 50 is written as 2× 5 × 5 or 2 × 5 2Now that we have done the prime factorization of our number, we can multiply them and get the other possible composite factors. 
50 = 2 × 5 × 5 = 2 × 52To get the total numbers of factors of 50:Add 1 to the exponents of 2 and 5, and multiply their sums: (1 + 1) × (2 + 1) = 2 x 3 = 6Thus, 50 has 6 factors and they are 1, 2, 5, 10, 25, and 50.
Pair factors of the number 50 are whole numbers which give the original number, i.e., 50 when multiplied.Pair factors can be either positive or negative but they cannot be a fraction or a decimal number.(1, 50 ), (-1, -50), (2, 25), (-2, -25), (5, 10), (-5, -10) 
Positive Factor PairsNegative Factor Pairs
1 × 50 -1 × -50 
2 × 25-2 × -25
5 × 10-5 × -10

Only whole numbers and integers can be factors.Only composite numbers can have more than two factors.Every factor of a given number is either less than or equal to the given number.

Example 1: What is the sum of all the factors of the number 50 including 50?

Solution:

Factors of 50: 1, 2, 5, 10, 25, 50

Sum of all the given factors = 1 + 2 + 5 + 10 + 25 + 50 = 93


Example 2: Write all the factors of 50 which are also the factors of 450.

Solution: 

Factors of 50 = 1, 2, 5, 10, 25, 50

Factors of 450 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

Hence, the common factors of 50 and 450 are 1, 2, 5, 25, and 50.
