Prime factorization of 1141: 13 × 37.

The sum of factors of 1141: 1 + 13 + 37 + 91 + 1141 = 1283

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

• Finding factors using multiplication
• Finding factors using 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 1141. Identifying the numbers which are multiplied to get the number 1141 is the multiplication method.

Step 1: Multiply 1141 by 1, 1141 × 1 = 1141.

Step 2: Check for other numbers that give 1141 after multiplying 13 × 37 = 1141

Therefore, the positive factor pairs of 1141 are: (1, 1141) and (13, 37).

All these factor pairs result in 1141.

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 in whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 1141 by 1, 1141 ÷ 1 = 1141.

Step 2: Continue dividing 1141 by the numbers until the remainder becomes 0.

1141 ÷ 1 = 1141

1141 ÷ 13 = 87.769 (not a factor)

1141 ÷ 37 = 30.838 (not a factor)

1141 ÷ 91 = 12.527 (not a factor)

1141 ÷ 13 = 87.769 (not a factor)

Therefore, the factors of 1141 are: 1, 13, 37, 91, and 1141.

The factors can be found by dividing it with a prime number. 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 1141 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1141 ÷ 13 = 87.769 (not a factor)

1141 ÷ 37 = 30.838 (not a factor)

The prime factors of 1141 are 13 and 37.

The prime factorization of 1141 is: 13 × 37.

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

Step 1: Start with 1141 and divide by its smallest prime factor, 13, to get 87.769 (not a factor).

Step 2: Try dividing 1141 by 37, which results in 30.838 (not a factor).

Hence, the prime factorization of 1141 is: 13 × 37.

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 1141: (1, 1141) and (13, 37).

Negative factor pairs of 1141: (-1, -1141) and (-13, -37).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1141 are 1, 13, 37, 91, and 1141.

• Prime factors: The factors which are prime numbers. For example, 13 and 37 are prime factors of 1141.

• 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 1141 are (1, 1141) and (13, 37).

• Prime factorization: The expression of a number as the product of its prime factors. For example, the prime factorization of 1141 is 13 × 37.

• Multiplication method: A method of finding factors by identifying pairs of numbers that multiply to give the original number.
