Question

let's calculator what is the biggest whole number of 4 digits which will be divisible by 12, 18 and 30.​

Answer 1

Answer:

The prime factors for each are

2×2×3=12

2×3×3=18

2×3×5=30

So the number in question must have. A factor of 180 ( 2×2×3×3×5 ), but 1802 exceeds four digits. Since 180=(65–√)2 , the best route is 302×n2.

The highest perfect square that 302 can be multiplied to, and still produce a four-digit number is 32.

302×32=8100

Verify:

810012=675

810018=450

810030=270

302×42=14400

So, the answer is 8100.
