Example 1:
Find the largest number of four digits divisible by 12, 15, 18, and 27.
Solution:
Largest four-digit number = 9999.
LCM(12, 15, 18, 27) = 540
540 * x are the numbers divisible by 12, 15, 18, and 27.
9999/540 leaves a remainder value of 279.
9999 – 279 = 9720
Example 2:
Find the smallest five-digit number divisible by 16, 24, 36, and 54.
Solution:
Smallest five-digit number = 10000.
LCM(16, 24, 36, 54) = 432
10000/432 gives the remainder 64.
(10000 – 64) + 432 = 10368
