Question

Hello brainly users
please answer to my question :)
All the best , its a bit difficult :p

Answer 1

● Hope this answer will help u
N + 1 is divisible by 2, 3, 4, 5, 6, 7, 8, 9 & 10 so clearly one solution would be 10! (ie 10*9*8*7*6*5*4*3*2 = 3628800 for N +1) but this is not the lowest possible. Follow the logic below... 

N + 1 must be a multiple of 2 

N + 1 must be a multiple of 4 but if it is a multiple of 2 & 4 it is necessarily a multiple of 8 

N + 1 must be a multiple of 5 but if it is a multiple of 2 & 5 it is necessarily a multiple of 10 

N + 1 must be a multiple of 6 but if it is a multiple of 2 & 9 (18) it is necessarily a multiple of 6 

N + 1 must be a multiple of 7 

N + 1 must be a multiple of 9 

Hence 2 x 4 x 5 x 7 x 9 = $\color{red}\mathcal{2520}$ is a multiple of 2, 3, 4, 5, 6, 7, 8, 9 & 10
