Answer»

We all know that largest 5 digit number = 99999

LCM of 8, 9, 10 and 12 = 360

99999 ÷ 360 = Remainder = 279

5 digit largest number DIVISIBLE by 8, 9 , 10 and 12 = 99999 – Remainder

5 digit largest number divisible by 8, 9, 10 and 12 = 99999 – 279 = 99720

∴ Required number = 99720 + 3 = 99723
