1. Steps to find factors of 151 using Division Method

Example: Find factors of 151

  • Divide 151 by 1: 151 ÷ 1 : Remainder = 0
  • Divide 151 by 151: 151 ÷ 151 : Remainder = 0

Hence, Factors of 151 are 1 and 151

2. Steps to find factors of 151 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 151 using the division method, follow these steps:

  • Step 1. Start dividing 151 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 151, which is 151. Divide 151 by 151 to obtain the quotient (1).
    151 ÷ 151 = 1
  • Step 3. Repeat step 1 with the obtained quotient (1).

So, the prime factorization of 151 is, 151 = 151.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 151 as shown below:

So, the prime factorization of 151 is, 151 = 151.

3. Find factors of 151 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 151 would be the two numbers which, when multiplied, give 151 as the result.

The following table represents the calculation of factors of 151 in pairs:

Factor Pair Pair Factorization
1 and 151 1 x 151 = 151

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 151. They are called negative pair factors.

Hence, the negative pairs of 151 would be ( -1 , -151 ) , .

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of factors

  • Every number is a factor of zero (0), since 151 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, 151 are exact divisors of 151.
  • Factors of 151 are 1, 151. Each factor divides 151 without leaving a remainder.
