Prime factorization of 1256: 2³ × 157.

The sum of factors of 1256: 1 + 2 + 4 + 8 + 157 + 314 + 628 + 1256 = 2370

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 1256. Identifying the numbers which are multiplied to get the number 1256 is the multiplication method.

Step 1: Multiply 1256 by 1, 1256 × 1 = 1256.

Step 2: Check for other numbers that give 1256 after multiplying

2 × 628 = 1256

4 × 314 = 1256

8 × 157 = 1256

Therefore, the positive factor pairs of 1256 are: (1, 1256), (2, 628), (4, 314), (8, 157). All these factor pair results in 1256. 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 1256 by 1, 1256 ÷ 1 = 1256.

Step 2: Continue dividing 1256 by the numbers until the remainder becomes 0.

1256 ÷ 1 = 1256

1256 ÷ 2 = 628

1256 ÷ 4 = 314

1256 ÷ 8 = 157

Therefore, the factors of 1256 are: 1, 2, 4, 8, 157, 314, 628, 1256.

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 1256 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1256 ÷ 2 = 628

628 ÷ 2 = 314

314 ÷ 2 = 157

157 ÷ 157 = 1

The prime factors of 1256 are 2 and 157. The prime factorization of 1256 is: 2³ × 157.

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

Step 1: Firstly, 1256 is divided by 2 to get 628.

Step 2: Now divide 628 by 2 to get 314.

Step 3: Then divide 314 by 2 to get 157. Here, 157 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1256 is: 2³ × 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 1256: (1, 1256), (2, 628), (4, 314), (8, 157).

• Negative factor pairs of 1256: (-1, -1256), (-2, -628), (-4, -314), (-8, -157).

• Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1256 are 1, 2, 4, 8, 157, 314, 628, and 1256.

• Prime factors: The factors which are prime numbers. For example, 2 and 157 are prime factors of 1256.

• 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 1256 are (1, 1256), (2, 628), etc.

• Prime factorization: The process of breaking down a number into its prime factors. For example, the prime factorization of 1256 is 2³ × 157.

• Negative factors: Factors that are negative whole numbers. For example, the negative factors of 1256 include -1, -2, -4, etc.
