What are the Factors of 140?

The following are the different types of factors of 140:

• Factors of 140: 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

• Negative Factors of 140: -1, -2, -4, -5, -7, -10, -14, -20, -28, -35, -70, -140

• Prime Factors of 140: 2, 5, 7

• Prime Factorization of 140: $2^2\times5^1\times7^1$

Factors by Division Method

To calculate the factors of 140, start by dividing the numbers by the smallest prime number, which is 2. If the number is not divisible by 2, proceed to the next prime number, such as 3, 5, 7, 11, 13, and continue this process until you reach 1.

Step 1: 140 ÷ 2 = 70
Step 2: 70 ÷ 2 = 35
Step 3: 35 ÷ 5 = 7
Step 4: 7 ÷ 7 = 1

In step 4, we have reached to 1, and so, the process is stopped.

• Prime Factors of 140: $2\times2\times5\times7$

• Prime Factorization of 140: $2^2\times5^1\times7^1$

The factors will be all the multiples of 1, 2, 2, 5, 7, 35, 70, 140

Calculating all the factors:
2 = 1 x 2
4 = 1 x 2 x 2
5 = 1 x 5
7 = 1 x 7
10 = 2 x 5
14 = 2 x 7
20 = 1 x 2 x 2 x 5
28 = 2 x 2 x 7
35 = 1 x 35
70 = 1 x 70
140 = 1 x 140

Finally Factors of 140 = 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
