Factors of 857

2. Steps to find factors of 857 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 857 using the division method, follow these steps:

• Step 1. Start dividing 857 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 857, which is 857. Divide 857 by 857 to obtain the quotient (1).
  857 ÷ 857 = 1
• Step 3. Repeat step 1 with the obtained quotient (1).

So, the prime factorization of 857 is, 857 = 857.

Method 2: Factor Tree Method

We can follow the same procedure using the factor tree of 857 as shown below:

So, the prime factorization of 857 is, 857 = 857.

3. Find factors of 857 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 857 would be the two numbers which, when multiplied, give 857 as the result.

The following table represents the calculation of factors of 857 in pairs:

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 857. They are called negative pair factors.

Hence, the negative pairs of 857 would be ( -1 , -857 ) , .

How do you explain factors?

In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.

Properties of factors

• Every factor of a number is an exact divisor of that number, example 1, 857 are exact divisors of 857.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Each number is a factor of itself. Eg. 857 is a factor of itself.
• 1 is a factor of every number. Eg. 1 is a factor of 857.
