Tricky Maths ! by https://padlet.com/ipthi_saif/uoc7jv0v49 Try Guessin' and Solvin'. . . . . Until u succeed :D 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. When I looked for a smaller number with this property I couldn't find one. Can you find it? en-us 2013-02-05 10:44:48 UTC 2025-11-14 20:20:56 UTC hello@padlet.com http://d2s8n7nv9yizdf.cloudfront.net/assets/thmbs/notebook-917a880d5d6f4a35c87d19b6a8c2333f.jpg Anusree anusreegovind https://padlet.com/ipthi_saif/uoc7jv0v49/wish/6912066 Is it 2519?

x+1 = 2520

x= 2520-1 = 2519

THEREFORE THE NUMBER IS 2519.

3 = 3
4 = 2^2
5 = 5
6 = 2 x 3
7 = 7
8 = 2^3
9 = 3^2
10 = 2 x5

LCM = 2^3 x 3^2 x 5 x 7
LCM = 8 x 6 x 5 x 7 = 2520.

The answer you want is
2520 - 1 = 2519.

2519/2 remainder =1

2519/3 " "=2

2519/4" "=3

2519/5 =4

2519/6 =5

2519/7 =6

2519/8 =7

2519/9 =8

2519/19 =9

remainders all become zero.  The smallest such number
divisible by 2 through 9 is the least common multiple of
2 through 9 which is 2520 = N + 1. Then, N = 2519.]]> 2013-02-11 18:25:38 UTC https://padlet.com/ipthi_saif/uoc7jv0v49/wish/7112462
