148+148+148=444

Units x, Tens y, Hundreds z

300z+30y+3x=100y+10y+y

300z+30y+3x=111y

300z+3x=81y

100z+x=27y equ 1

x, y, z are all integers and all less then 10

Trial and error

27*9=243 when y=9 but then x =43 not possible

Similarly for others

24*4=108 when y=4, z=1, x=8

Therefore the number is 148
