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 1547. Identifying the numbers which are multiplied to get the number 1547 is the multiplication method.

Step 1: Multiply 1547 by 1, 1547 × 1 = 1547.

Step 2: Check for other numbers that give 1547 after multiplying

7 × 221 = 1547

13 × 119 = 1547

19 × 81 = 1547

Therefore, the positive factor pairs of 1547 are: (1, 1547), (7, 221), (13, 119), (19, 81). All these factor pair result in 1547. 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 1547 by 1, 1547 ÷ 1 = 1547.

Step 2: Continue dividing 1547 by the numbers until the remainder becomes 0.

1547 ÷ 1 = 1547

1547 ÷ 7 = 221

1547 ÷ 13 = 119

1547 ÷ 19 = 81

Therefore, the factors of 1547 are: 1, 7, 13, 19, 91, 133, 247, 1547.

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 1547 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1547 ÷ 7 = 221

221 ÷ 13 = 17

17 ÷ 19 = 1

The prime factors of 1547 are 7, 13, and 19. The prime factorization of 1547 is: 7 × 13 × 19.

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

Step 1: Firstly, 1547 is divided by 7 to get 221.

Step 2: Now divide 221 by 13 to get 17.

Step 3: Then divide 17 by 19 to get 1. Here, 1 is the endpoint of the factorization tree. So, the prime factorization of 1547 is: 7 × 13 × 19.

Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.
