Answer 1

Answer:  10080

Step-by-step explanation:

First ,we find the LCM of 60 ,80,90

now, we get the LCM of 60, 80, 90 =720.

The smallest number of five digits =10000

Let us divide 10000 by the LCM (720).

720)10000( 13

-720

.........

2800

-2160

............

640

The required number =10000 - remainder + LCM

=10000 - 640 + 720

= 10720 - 640

= 10080

Hence, 10080 is the smallest five digit number which is exactly divisible by 60,80,90.
