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

What is the greatest common divisor of 189 567 and 2187?
A mathemtical trick is to note that all three numbers are divisible by '9'. How do we known this?? Because the sum of the digits in each number adds to '9'. Hence 189, 567, 2187) 189 ; 1 + 8 + 9 = 18 = 1 + 8 = 9 567 ; 5 + 6 + 7 = 18 = 1 + 8 = 9 2187 [ 2 + 1 + 8 + 7 = 18 = 1 + 8 = 9 189/9 = 21 567/ 9 = 63 2187/9 = 243 All three sub-answer will divide by '3' Hence 7,9,81 ( There are NO common factors ) Hence 9 x 3 = 27 is the GCF. NB THis mathemtical 'trick' can only be done with '9'. !!!!!
What is the exponential form of 2187?
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.
What is the LCM of 297 891 and 2187?
The LCM is 24057.
