The multiplication method finds the pair of factors that give 620 as their product.

Step 1: Find the pair of numbers whose product is 620.
Step 2: The factors are those numbers that, when multiplied, give 620.
Step 3: Make a list of numbers whose product will be 620.

A list of numbers whose products are 620 is given below:

• 1 × 620 = 620
• 2 × 310 = 620
• 4 × 155 = 620
• 5 × 124 = 620
• 10 × 62 = 620
• 20 × 31 = 620
   

The division method finds the numbers that fully divide the given number. The steps are given below:

Step 1: Since every number is divisible by 1, 1 will always be a factor.

Example: 620 ÷ 1 = 620

Step 2: Move to the next integer. The factors of the number include the number that is used to divide and the number of times the particular number is divided.
 

Multiplying prime numbers to get the given number as their product is called prime factors. A number when it is simplified using the factors of that number and is expressed in the form of prime factors is the prime factorization of a number.

Prime Factors of 620: Number 620 has the prime factors 2, 5, and 31.

To find the prime factors of 620, we can divide 620 with the prime numbers like 2, 5, and 31 from the list of factors of 620.

Step 1: Divide 620 by the prime number 2
620 ÷ 2 = 310

Step 2: Divide 310 by the prime number 2
310 ÷ 2 = 155

Step 3: Divide 155 by the prime number 5
155 ÷ 5 = 31

Step 4: Divide 31 by the prime number 31
31 ÷ 31 = 1

The prime factorization is visually represented using the factor tree. It helps to understand the process easily.
This tree shows the breakdown of 620 into its prime factors: 2 × 2 × 5 × 31.

In this factor tree, each branch splits into prime factors.

Factors of 620 can be written in both positive pairs and negative pairs. They are like team members. Their product will be equal to the number given.

Positive Factor Pairs: (1, 620), (2, 310), (4, 155), (5, 124), (10, 62), (20, 31)
Negative Factor Pairs: (-1, -620), (-2, -310), (-4, -155), (-5, -124), (-10, -62), (-20, -31)
 

• Factor: A number that divides another number completely without leaving a remainder. For example, 1, 2, 4, 5, etc., are factors of 620.

• Prime Factorization: The process of breaking down a number into its prime factors, expressed in the form of multiplication of prime numbers. For 620, the prime factorization is 2² × 5 × 31.

• Perfect Square: A number that results from multiplying the same number by itself. For example, 4 (2 × 2) is a perfect square and a factor of 620.

• Co-prime: Two numbers that have 1 as their only common factor. For example, 31 and 62 are not co-prime as their greatest common factor (GCF) is 31.

• Multiple: A number that is the product of another number and an integer. For example, 620 is a multiple of 5 because 620 ÷ 5 = 124 with no remainder.
