How to Find the Factors of 266?

To find the factors of 266, we will have to find the list of numbers that would divide 266 without leaving any remainder.

• 266/14 = 19; therefore, 14 is a factor of 266 and 19 is also a factor of 266.
• 266/38 = 7; therefore, 38 is a factor of 266 and 7 is also a factor of 266.

Similarly we can find other factors. Hence, the factors of 266 are 1, 2, 7, 14, 19, 38, 133, 266.

• Factors of 65 - The factors of 65 are 1, 5, 13, 65
• Factors of 8 - The factors of 8 are 1, 2, 4, 8
• Factors of 32 - The factors of 32 are 1, 2, 4, 8, 16, 32
• Factors of 42 - The factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42

The number 266 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 266. The first step is to divide the number 266 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.

• 266 ÷ 2 = 133

Further dividing 133 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 133 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 266 can be written as 2¹ × 7¹ × 19¹ where 2, 7, 19 are prime.

Pair factors of 266 are the pairs of numbers that when multiplied give the product 266. The factors of 266 in pairs are:

• 1 × 266 = (1, 266)
• 2 × 133 = (2, 133)
• 7 × 38 = (7, 38)
• 14 × 19 = (14, 19)

Negative pair factors of 266 are:

• -1 × -266 = (-1, -266)
• -2 × -133 = (-2, -133)
• -7 × -38 = (-7, -38)
• -14 × -19 = (-14, -19)

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