How to Find the Factors of 166?

To find the factors of 166, we will have to find the list of numbers that would divide 166 without leaving any remainder.

• 166/83 = 2; therefore, 83 is a factor of 166 and 2 is also a factor of 166.
• 166/1 = 166; therefore, 1 is a factor of 166 and 166 is also a factor of 166.

Similarly we can find other factors. Hence, the factors of 166 are 1, 2, 83, 166.

• Factors of 100 - The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100
• Factors of 35 - The factors of 35 are 1, 5, 7, 35
• Factors of 30 - The factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30

The number 166 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 166. The first step is to divide the number 166 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.

• 166 ÷ 2 = 83

Further dividing 83 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 83 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.

So, the prime factorization of 166 can be written as 2¹ × 83¹ where 2, 83 are prime.

Pair factors of 166 are the pairs of numbers that when multiplied give the product 166. The factors of 166 in pairs are:

• 1 × 166 = (1, 166)
• 2 × 83 = (2, 83)

Negative pair factors of 166 are:

• -1 × -166 = (-1, -166)
• -2 × -83 = (-2, -83)

NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
