Negative factors of 1570: -1, -2, -5, -10, -157, -314, -785, and -1570.

Prime factors of 1570: 2, 5, and 157.

Prime factorization of 1570: 2 × 5 × 157.

The sum of factors of 1570: 1 + 2 + 5 + 10 + 157 + 314 + 785 + 1570 = 2844

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

1. Finding factors using multiplication
2. Finding factors using the 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 1570. Identifying the numbers which are multiplied to get the number 1570 is the multiplication method.

Step 1: Multiply 1570 by 1, 1570 × 1 = 1570.

Step 2: Check for other numbers that give 1570 after multiplying

2 × 785 = 1570

5 × 314 = 1570

10 × 157 = 1570

Therefore, the positive factor pairs of 1570 are: (1, 1570), (2, 785), (5, 314), (10, 157). All these factor pairs result in 1570. 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 that result in whole numbers as factors. Factors can be calculated by following the simple division method -

Step 1: Divide 1570 by 1, 1570 ÷ 1 = 1570.

Step 2: Continue dividing 1570 by the numbers until the remainder becomes 0.

1570 ÷ 1 = 1570

1570 ÷ 2 = 785

1570 ÷ 5 = 314

1570 ÷ 10 = 157

Therefore, the factors of 1570 are: 1, 2, 5, 10, 157, 314, 785, 1570.

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 1570 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1570 ÷ 2 = 785

785 ÷ 5 = 157

157 ÷ 157 = 1

The prime factors of 1570 are 2, 5, and 157. The prime factorization of 1570 is: 2 × 5 × 157.

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

Step 1: Firstly, 1570 is divided by 2 to get 785.

Step 2: Now divide 785 by 5 to get 157.

Step 3: Divide 157 by 157 to get 1. Here, 157 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1570 is: 2 × 5 × 157.

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 1570: (1, 1570), (2, 785), (5, 314), (10, 157).

• Negative factor pairs of 1570: (-1, -1570), (-2, -785), (-5, -314), (-10, -157).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1570 are 1, 2, 5, 10, 157, 314, 785, and 1570.

• Prime factors: The factors which are prime numbers. For example, 2, 5, and 157 are prime factors of 1570.

• 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 1570 are (1, 1570), (2, 785), etc.

• Prime factorization: Breaking down a number into its prime factors. For example, the prime factorization of 1570 is 2 × 5 × 157.

• Multiple: A product of a number and an integer. For example, 1570 is a multiple of 157.
