The smallest number which gives the remainder of 1 when divided of any of the numbers is the LCM of the numbers + 1
i.e. LCM + 1

Which is 61

why????

Because LCM is the smallest number divisible by all the given numbers...........and to have the remainder of 1 then add 1 to the LCM

2 = 1*2
3 = 1*3
4 = 1*2*2
5 = 1*5
6 = 1*2*3
so
LCM = 1*2*2*3*5 = 60
LCM + 1 = 61

So the number is 61

Can you find a number such that if we multiply that number by 1 or 2 or 3 or 4 or 5 or 6, then the resultant number contains same all digits (of course in a different place)
