1=5, 2=25, 3=325, 4=4325, 5=1
if 1=5, 2=25, 3=325, 4=4325, 5=1 !! Isn't that simple? :-)
next number to this series is 554325. its look like this 15--add 1 to first digit and we get 2 and repeat two times and leave other digit.225 225-- its first digit is 2 and add 1 to it get 3 and write two time and write remaining digit as 3325. 3325-- its first digit is 3 and add 1 to it get 4 and write two time and write remaining digit as 44325. 44325-- its first digit is 4 and add 1 to it get 3 and write two time and write remaining digit as 554325.
You can take 225 to 15 and 15. Then take 15 to 3 and 5. So, you have 3, 3, 5, 5.
The factor tree of 225 is: 15, 15 3, 5, 3, 5 225 75,3 25,3,3 5,5,3,3
The factor pairs of 225 are 1 x 225, 3 x 75, 5 x 45, 9 x 25, and 15 x 15
It is: 5*5*7*19 = 3325 or as 52*7*19 = 3325
1, 3, 5, 9, 15, 25, 45, 75, 225 (1 x 225, 3 x 75, 5 x 45, 9 x 25, 15 x 15).
Divide 225 by 1, 3, 5, 9 and 15. 1, 3, 5, 9, 15, 25, 45, 75, 225
Factor out each term to get: 225 = 15 * 15 = 3² * 5² 165 = 15 * 11 = 3 * 5 * 11 Then, the GCF is 3 * 5 = 15 since that is the greatest term which divides both 225 and 165!
