Factors of 250

In Mathematics, factors of 250 are the natural numbers by which the original number can be evenly divided.

They are also called divisors of 250 since they divide the original number. Although 250 is a multiple of 25, it is not a perfect square. Moreover, 250 is divisible by 5 (by divisibility rules).

When the multiplication of two natural numbers equals 250, they are the necessary factors of 250. A composite number with an even number factor is 250.

Let’s identify the factors of 250 as well as the prime and pair factors.

What are Factors of -250?

When we multiply two numbers, and we get -250 as a product, that numbers are the factors of -250. 

Here is the explanation:

-1 × 250 = -250

 1 × -250 = -250 

 -2 × 125 = -250

 2 × -125 = -250

 -5 × 50 = -250 

 5 × -50 = -250

 -10 × 25 = -250

 10 × -25 = -250

We can get -250 by having (-1, 250), (-2, 125), (-5, 50), and (-10, 25) as a pair of factors. Similarly, we can also get -250 by having(1, -250), (2, -125), (5, -50), and (10, -25) as a pair of factors.

How to Find the Factors of 250?

Finding the factors of 250 is easy. In order to divide 250 evenly, we must divide it by all such natural numbers. Alternatively, you can multiply these two numbers together to get 250.

Division MethodMultiplication Method
250 ÷ 1 = 2501 × 250 = 250
250 ÷ 2 = 1252 × 125 = 250
250 ÷ 5 = 505 × 50 = 250
250 ÷ 10 = 2510 × 25 = 250
250 ÷ 25 = 1025 × 10 = 250
250 ÷ 50 = 550 × 5 = 250
250 ÷ 225 = 2225 × 5 = 250
250 ÷ 250 = 1250 × 1 = 250

Thus, the factors of 250 are 1, 2, 5, 10, 25, 50, 125, 250.

Pair Factors of 250

When two integers are multiplied by each other to result in 250, then they have required pair factors. Then,

1 × 250 = 250

2 × 125 = 250

5 × 50 = 250

10 × 25 = 250

Thus, the pair factors of 250 are (1, 250), (2, 125), (5, 50), and (10, 25).

To get the factors in pairs, we can find the product of two negative numbers:

-1 × -250 = 250

-2 × -125 = 250

-5 × -50 = 250

-10 × -25 = 250

Thus, the negative pair factors are (-1, -250), (-2, -125), (-5, -50), (-10, -25).

Prime Factorization of 250

If we prime factorize 250, we will get prime factors that divide the original number evenly.

Dividing 250 by the smallest prime number250 ÷ 2 = 125
Again, dividing 125 by the smallest prime number125 ÷ 5 = 25
Dividing 25 by 525 ÷ 5 = 5
Again, dividing 5 by 55 ÷ 5 = 1

Therefore, the prime factors of 250 are 2 and 5.
