Question

Find the five digit number that is exactly divided by 60,90,80

Answer 1

Answer:

I should be even 5 digit number

so , ans =20,000

Answer 2

Answer:

The way to do this is find the LCM (lowest common multiple) turn multiply by the smallest number you can that'll make it 5 digits.

The LCM of 60, 90 and 80 is 720

Multiplying 720 by 10 gives 7200 so it must be more than 10. 720*20 is 14400 which is definitely too much since 14400–720=13680 which is still 5 digits. 720*14 is the correct answer because 720*13 is under 10,000

Therefore the answer is 720*14 or 10080
