Question

10. Find the greatest number of 4-digits which is exactly divisible by 30,36, and 60.​

Answer 1

Answer:

888 is the greatest digit

Answer 2

Answer:

9840

Step-by-step explanation:

first of all we find L.C.M. of 40,48,60 =240

so the number will be divisible by 240

as we observe that number will surely divisible by 10

so we find out three digit maximum number divisible by 24

so lets try 999 we can see that after dividing it by 24 we get

2

999=24(31)+15=984+15

so finally we got 984 which is diisible by 24 and 9840 which is divisible by 240,40,48,60

so the answer is 9840
