RIGHT CLICK SELECT ALL FOR SOLUTION :
I just found a number with an interesting property:
When I divide it by 2, the remainder is 1.
When I divide it by 3, the remainder is 2.
When I divide it by 4, the remainder is 3.
When I divide it by 5, the remainder is 4.
When I divide it by 6, the remainder is 5.
When I divide it by 7, the remainder is 6.
When I divide it by 8, the remainder is 7.
When I divide it by 9, the remainder is 8.
When I divide it by 10, the remainder is 9.
It's not a small number, but it's not really big, either.
Find the smallest number with such property.
2519
All we need to do is to take the LCM of all these numbers and subtract 1 from that..
LCM of 1 to 10 is 5x8x9x7=2520
-1 is 2519
