13 times.
13 x 6 x 3 = 234
18 times.
13 is a prime number and thus the the LCM of 13 and any number is 13 times that number. The LCM is: 234
13
Since 13 is a prime number, and 18 is the LCM of 9 and 18, then 13*18 = 234 is the LCM of 13, 9, and 18.
The LCM is 234.
234/270 = 13/15
18
234 ÷ 13 = 18
10000 * 234 = 2,340,000
234 * 22 = 5,148
