Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 890, how they are used in real life, and tips to learn them quickly.

What are the Factors of 890?

The numbers that divide 890 evenly are known as factors of 890.

A factor of 890 is a number that divides the number without remainder.

The factors of 890 are 1, 2, 5, 10, 89, 178, 445, and 890.

Negative factors of 890: -1, -2, -5, -10, -89, -178, -445, and -890.

Prime factors of 890: 2, 5, and 89.

Prime factorization of 890: 2 × 5 × 89.

The sum of factors of 890: 1 + 2 + 5 + 10 + 89 + 178 + 445 + 890 = 1620

How to Find Factors of 890?

Factors can be found using different methods. Mentioned below are some commonly used methods:

  • Finding factors using multiplication
     
  • Finding factors using the division method
     
  • Prime factors and Prime factorization

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 890. Identifying the numbers which are multiplied to get the number 890 is the multiplication method.

Step 1: Multiply 890 by 1, 890 × 1 = 890.

Step 2: Check for other numbers that give 890 after multiplying     

2 × 445 = 890     

5 × 178 = 890     

10 × 89 = 890

Therefore, the positive factor pairs of 890 are: (1, 890), (2, 445), (5, 178), (10, 89).

All these factor pairs result in 890.

For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 890 by 1, 890 ÷ 1 = 890.

Step 2: Continue dividing 890 by the numbers until the remainder becomes 0.

890 ÷ 1 = 890

890 ÷ 2 = 445

890 ÷ 5 = 178

890 ÷ 10 = 89

Therefore, the factors of 890 are: 1, 2, 5, 10, 89, 178, 445, 890.

Prime Factors and Prime Factorization

The factors can be found by dividing them with prime numbers. We can find the prime factors using the following methods:
 

Using Prime Factorization: In this process, prime factors of 890 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

890 ÷ 2 = 445

445 ÷ 5 = 89

89 ÷ 89 = 1

The prime factors of 890 are 2, 5, and 89.

The prime factorization of 890 is: 2 × 5 × 89.

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -

Step 1: Firstly, 890 is divided by 2 to get 445.

Step 2: Now divide 445 by 5 to get 89.

Step 3: Here, 89 is a prime number, which cannot be divided anymore.

So, the prime factorization of 890 is: 2 × 5 × 89.

Factor Pairs Two numbers that are multiplied to give a specific number are called factor pairs.

Both positive and negative factors constitute factor pairs.

Positive factor pairs of 890: (1, 890), (2, 445), (5, 178), (10, 89).

Negative factor pairs of 890: (-1, -890), (-2, -445), (-5, -178), (-10, -89).

Common Mistakes and How to Avoid Them in Factors of 890

Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.

Problem 1

There are 10 friends and 890 apples. How will they divide them equally?

Okay, lets begin

They will get 89 apples each.

Explanation

To divide the apples equally, we need to divide the total apples with the number of friends.

890/10 = 89

Problem 2

A plot is rectangular, the length of the plot is 178 meters and the total area is 890 square meters. Find the width?

Okay, lets begin

5 meters.

Explanation

To find the width of the plot, we use the formula,     

Area = length × width     

890 = 178 × width     

To find the value of width, we need to shift 178 to the left side.     

890/178 = width     

Width = 5.
