Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 489. Identifying the numbers which are multiplied to get the number 489 is the multiplication method. Step 1: Multiply 489 by 1, 489 × 1 = 489. Step 2: Check for other numbers that give 489 after multiplying 3 × 163 = 489 Therefore, the positive factor pairs of 489 are: (1, 489) and (3, 163). All these factor pairs result in 489. For every positive factor, there is a negative factor.

Finding Factors Using Division Method

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 simple division methods - Step 1: Divide 489 by 1, 489 ÷ 1 = 489. Step 2: Continue dividing 489 by the numbers until the remainder becomes 0. 489 ÷ 1 = 489 489 ÷ 3 = 163 Therefore, the factors of 489 are: 1, 3, 163, 489.

Prime Factors and Prime Factorization

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 489 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1. 489 ÷ 3 = 163 163 ÷ 163 = 1 The prime factors of 489 are 3 and 163. The prime factorization of 489 is: 3 × 163.

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows - Step 1: Firstly, 489 is divided by 3 to get 163. Step 2: 163 is a prime number, so it cannot be divided further. So, the prime factorization of 489 is: 3 × 163. 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 489: (1, 489) and (3, 163). Negative factor pairs of 489: (-1, -489) and (-3, -163).
