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

1. Finding factors using multiplication
2. Finding factors using division method
3. Prime factors and Prime factorization

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 1577. Identifying the numbers which are multiplied to get the number 1577 is the multiplication method.

Step 1: Multiply 1577 by 1, 1577 × 1 = 1577.

Step 2: Check for other numbers that give 1577 after multiplying 37 × 43 = 1577

Therefore, the positive factor pairs of 1577 are: (1, 1577) and (37, 43). All these factor pairs result in 1577. For every positive factor, there is a negative factor.

Dividing the given numbers with 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 the simple division method -

Step 1: Divide 1577 by 1, 1577 ÷ 1 = 1577.

Step 2: Continue dividing 1577 by the numbers until the remainder becomes 0.

1577 ÷ 1 = 1577

1577 ÷ 37 = 43

1577 ÷ 43 = 37

Therefore, the factors of 1577 are: 1, 37, 43, 1577.

The factors can be found by dividing it 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 1577 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1577 ÷ 37 = 43

43 ÷ 43 = 1

The prime factors of 1577 are 37 and 43. The prime factorization of 1577 is: 37 × 43.

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

Step 1: Firstly, 1577 is divided by 37 to get 43.

Step 2: Now divide 43 by 43 to get 1. Here, 43 is the final prime number, that cannot be divided anymore. So, the prime factorization of 1577 is: 37 × 43.

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 1577: (1, 1577) and (37, 43).

• Negative factor pairs of 1577: (-1, -1577) and (-37, -43).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1577 are 1, 37, 43, and 1577.

• Prime factors: The factors which are prime numbers. For example, 37 and 43 are prime factors of 1577.

• Prime factorization: Expressing a number as a product of its prime factors. For example, the prime factorization of 1577 is 37 × 43.

• 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 1577 are (1, 1577) and (37, 43).

• Divisibility: The condition of being divisible by a number without leaving a remainder. For example, 1577 is divisible by 37.
