Explicație pas cu pas:
n = 24C1 + 17
n = 32C2 + 25
n = 40C3 + 33
n + 7 = 24C1 + 17 + 7 = 24C1 + 24 = 24(C1 + 1)
n + 7 = 32C2 + 25 + 7 = 32C2 + 32 = 32(C2 + 1)
n + 7 = 40C3 + 33 + 7 = 40C3 + 40 = 40(C3 + 1)
24 = 2^3*3
32 = 2^5
40 = 2^3*5
cmmmc (24, 32, 40) = 2^5*3*5 = 480
n + 7 = 480
n = 480 - 7 = 473
