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

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

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.

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.

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

• Using prime factorization
   
• Using factor tree

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.

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).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 890 are 1, 2, 5, 10, 89, 178, 445, and 890.
  
   
• Prime Factors: The factors which are prime numbers. For example, 2, 5, and 89 are prime factors of 890.
  
   
• Factor pairs: Two numbers in a pair that are multiplied to give the original number are called factor pairs. For example, the factor pairs of 890 are (1, 890), (2, 445), etc.
  
   
• Prime Factorization: The process of expressing a number as the product of its prime factors. For example, the prime factorization of 890 is 2 × 5 × 89.
  
   
• Multiplication Method: A technique to find factors by identifying pairs of numbers that multiply to give the original number. For instance, using this method to find factors of 890 yields pairs like (1, 890) and (10, 89).
