Since 2187is an ODD Number, try the lowest odd prime number '3'. Hence 3)2187 729 Keep on dividing by '3', until it will go no further, then try the next prime number '5'. Keep on doing this until you reduce to '1' . Hence 3)729 3)243 3)81 3)27 3)9 3)3 =1 Reduced to '1'. We have divided by '3' seven times over. Hence 2187 = 3^(7)_ The answer!!!!! NB Division by other prime numbers was not needed. NNB Use this 'step-ladder' system to find all the fctors/exponents of a given number.
2 to the power of 3 equals 8.

3^7 = 2187
It is: 10 because 10^3 = 1000

You multiply it by itself repeatedly. For example, 37 = 3*3*3*3*3*3*3 = 2187
1024 = 2 to the power 10, 2187 = 3 to the power 7. There is no common factor above 1.
3 to the 2nd power times 3 to the 5th power = 3x3 x 3x3x3x3x3 = 2187

6561. (3*3*3*3*3*3*3*3=6561)
The number that, when raised to the third power, equals 27 is 3. This is because (3^3 = 3 \times 3 \times 3 = 27). Therefore, the answer is 3.
2 to the power of 3 equals 8.

if we list the prime factors of both numbers we get the following: 2187 : 3 3 3 3 3 3 3 135405: 3 3 3 5 17 59 We can then take the product of whatever factors they both share. Since they both have 3 3's the product is 27. This means that 27 is the largest number that will divide both 2187 and 135405
The number is -3
1, 3, 9, 27, 81, 243, 729, 2187.
