Determine the largest number of four digits which is divisible by 18,25,and 35

4 answers

18 = 2 3^2
25 = 5^2
35 = 5 7

So, the LCM is 2 * 3^2 * 5^2 * 7 = 3150
3150*2 = 6300
3150*3 = 9450
I expect that is the largest 4-digit multiple.
If we decide 3150 with 18,25 and 35 so our question will be solved. 👍
