Step-by-step explanation:
Smallest number divisible by 18,24,32
Factors of 18=2×3×3
Factors of 24=2×3×2×2
Factors of 32=2×2×2×2×2
LCM=2×2×2×2×2×3×3=288
∴288 is the smallest number divisible by 18,24,32
Now, smallest 4 digit number=1000
1000=288×3+136
Remainder=136
But we need to find a number where the remainder is 0
Required number=1000+(288−136)=1000+152=1152
So,1152 is the smallest 4 digit number.
