How do you find the smallest divisible number?
Smallest number divisible by first n numbers
- Initialize ans = 1.
- Iterate over all the numbers from i = 1 to i = n. At the i’th iteration ans = LCM(1, 2, …….., i). This can be done easily as LCM(1, 2, …., i) = LCM(ans, i). Thus at i’th iteration we just have to do –
What is the smallest number divisible by 2 3 4 and 5?
Assuming you mean smallest *positive* integer divisible by 2,3,4,5,6, the answer is LCM(2,3,4,5,6) = 60.
What is the smallest number divisible by 585 and 624?
Smallest number divisible by 585 and 624 is 9360.
What is the least number divisible by 2 3 4 5 and 7?
301 is divisible by 7. Therefore 301 is the least number which leaves remainder as 1 when divided by 2, 3, 4, 5, 6 and leaves no remainder when divided by 7.
What is the most divisible number?

What is the smallest number exactly divisible by 14 and 28?
L.C.M of 14 and 28 is 28 itself. thus , The smallest number exactly divisible by 14 and 28 is 28.
What is the smallest 5 digit number exactly divisible by 72 and 108?
Now in this number add 216, which is the required smallest 5 digit number which is exactly divisible by 72 and 108. So the smallest 5 digit number is = 9936 + 216 = 10152. So this is the required answer.
