Question

find the least 5-digit number which is excactly divisible by 20, 25. 30.

Answer 1

Answer:

15000

Step-by-step explanation:

the least 5 digit number is 10000

10000 is divisible by 20 and 25 but not divisible by 30

so lets multiply 30 with 10000

by doing so we get 300000

but this number has 6 digits so lets cancel one zero

now we have 30000 which is a 5 digit but 15000 can also be divided

and there is no other number lesser than 15000 which can be divided by 20, 25 and 30.

therefore 15000 is the least 5 digit number that can be divided by 20, 25 and 30.

Answer 2

10200 is exactly divisible by 20 30 and 25

10200/20 = 510
10200/25 = 408
10200/30 = 340

Hope it helps :))
