Question

the greatest no of 4 digits divide by 68,18,34,45​

Answer 1

Here,

• LCM of 68, 18, 34, 45 →

$68 = 2 \times 2 \times 17 \\ 18 = 2 \times 3 \times 3 \\ 34 = 2 \times 17 \\ 45 = 3 \times 3 \times 5$

And,

• LCM = 2 × 2 × 3 × 3 × 5 × 17 = 3060

Thus,

• 3060 is the greatest 4 digit number divisible by 68, 18, 34, 45.
