Negative factors of 647: -1 and -647.

Prime factors of 647: 647 (since it is a prime number).

Prime factorization of 647: 647.

The sum of factors of 647: 1 + 647 = 648

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 647. Identifying the numbers which are multiplied to get the number 647 is the multiplication method.

Step 1: Multiply 647 by 1, 647 × 1 = 647.

Since 647 is a prime number, no other positive factor pairs exist apart from (1, 647). 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 in whole numbers as factors. Factors can be calculated by following a simple division method:

Step 1: Divide 647 by 1, 647 ÷ 1 = 647.

Step 2: Since 647 is a prime number, it will not be divisible by any other number except 647. Therefore, the factors of 647 are: 1 and 647.

The factors can be found by dividing 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 647 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

Since 647 is a prime number, it cannot be broken down further. The prime factorization of 647 is: 647.

The factor tree is the graphical representation of breaking down any number into prime factors. Since 647 is a prime number, it cannot be broken down further using a factor tree. The prime factorization of 647 is: 647.

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 647: (1, 647).
• Negative factor pairs of 647: (-1, -647).

• Factors: The numbers that divide a given number without leaving a remainder are called factors. For example, the factors of 647 are 1 and 647.

• Prime factors: The factors which are prime numbers. For example, 647 is a prime factor of itself.

• Factor pairs: Two numbers in a pair that are multiplied to give the original number are called factor pairs. For example, the factor pair of 647 is (1, 647).

• Prime number: A number greater than 1 with no divisors other than 1 and itself. For example, 647 is a prime number.

• Division method: A method to find factors by dividing the number by whole numbers. For example, dividing 647 by 1 gives 647, confirming both as factors.
