2. Steps to find factors of 4900 using Prime Factorization

A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.

There are two different methods that can be used for the prime factorization.

Method 1: Division Method

To find the primefactors of 4900 using the division method, follow these steps:

  • Step 1. Start dividing 4900 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
  • Step 2. After finding the smallest prime factor of the number 4900, which is 2. Divide 4900 by 2 to obtain the quotient (2450).
    4900 ÷ 2 = 2450
  • Step 3. Repeat step 1 with the obtained quotient (2450).
    2450 ÷ 2 = 1225
    1225 ÷ 5 = 245
    245 ÷ 5 = 49
    49 ÷ 7 = 7
    7 ÷ 7 = 1

So, the prime factorization of 4900 is, 4900 = 2 x 2 x 5 x 5 x 7 x 7.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 4900 as shown below:

So, the prime factorization of 4900 is, 4900 = 2 x 2 x 5 x 5 x 7 x 7.

3. Find factors of 4900 in Pairs

Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 4900 would be the two numbers which, when multiplied, give 4900 as the result.

The following table represents the calculation of factors of 4900 in pairs:

Factor Pair Pair Factorization
1 and 4900 1 x 4900 = 4900
2 and 2450 2 x 2450 = 4900
4 and 1225 4 x 1225 = 4900
5 and 980 5 x 980 = 4900
7 and 700 7 x 700 = 4900
10 and 490 10 x 490 = 4900
14 and 350 14 x 350 = 4900
20 and 245 20 x 245 = 4900
25 and 196 25 x 196 = 4900
28 and 175 28 x 175 = 4900
35 and 140 35 x 140 = 4900
49 and 100 49 x 100 = 4900
50 and 98 50 x 98 = 4900
70 and 70 70 x 70 = 4900

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 4900. They are called negative pair factors.

Hence, the negative pairs of 4900 would be ( -1 , -4900 ) , ( -2 , -2450 ) , ( -4 , -1225 ) , ( -5 , -980 ) , ( -7 , -700 ) , ( -10 , -490 ) , ( -14 , -350 ) , ( -20 , -245 ) , ( -25 , -196 ) , ( -28 , -175 ) , ( -35 , -140 ) , ( -49 , -100 ) , ( -50 , -98 ) and ( -70 , -70 ) .

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of factors

  • Each number is a factor of itself. Eg. 4900 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 4900.
  • Every number is a factor of zero (0), since 4900 x 0 = 0.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Every factor of a number is an exact divisor of that number, example 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 49, 50, 70, 98, 100, 140, 175, 196, 245, 350, 490, 700, 980, 1225, 2450, 4900 are exact divisors of 4900.
