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'. !!!!!
