How to Find the Factors of 2187?

To find the factors of 2187, we will have to find the list of numbers that would divide 2187 without leaving any remainder.

• 2187/9 = 243; therefore, 9 is a factor of 2187 and 243 is also a factor of 2187.
• 2187/3 = 729; therefore, 3 is a factor of 2187 and 729 is also a factor of 2187.

Similarly we can find other factors. Hence, the factors of 2187 are 1, 3, 9, 27, 81, 243, 729, 2187.

• Factors of 10 - The factors of 10 are 1, 2, 5, 10
• Factors of 55 - The factors of 55 are 1, 5, 11, 55
• Factors of 45 - The factors of 45 are 1, 3, 5, 9, 15, 45
• Factors of 28 - The factors of 28 are 1, 2, 4, 7, 14, 28

The number 2187 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 2187. The first step is to divide the number 2187 with the smallest prime factor, here it is 3. We keep dividing until it gives a non-zero remainder.

• 2187 ÷ 3 = 729
• 729 ÷ 3 = 243
• 243 ÷ 3 = 81
• 81 ÷ 3 = 27
• 27 ÷ 3 = 9
• 9 ÷ 3 = 3
• 3 ÷ 3 = 1

Further dividing 1 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 1 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.

Since, we can't divide any further in this case so we stop.

So, the prime factorization of 2187 is 3⁷.

Pair factors of 2187 are the pairs of numbers that when multiplied give the product 2187. The factors of 2187 in pairs are:

• 1 × 2187 = (1, 2187)
• 3 × 729 = (3, 729)
• 9 × 243 = (9, 243)
• 27 × 81 = (27, 81)

Negative pair factors of 2187 are:

• -1 × -2187 = (-1, -2187)
• -3 × -729 = (-3, -729)
• -9 × -243 = (-9, -243)
• -27 × -81 = (-27, -81)

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