Question

find the greatest number of four digits which is exactly divisible by 15 24 and 36​

Answer 1

Step-by-step explanation:

First we find the Lcm of 15;24;36. is 360. we know that greatest 4 digits no. is 9999. And then 9999/360=279 is the remainder. Then 9999-279=9720.. is the ans.

Answer 2

Answer:

is 9720

Step-by-step explanation:

given : 15 , 24 , 36

first find the prime factorization of 15 ,24 ,36

15 = 3 x 5

24 = 2 x 2 x 2 x 3

36 = 2 x 2 x 3 x 3

L.C.M OF 15 24 36 = 2 x 2 x 2 x 3 x 3 x 5 = 360

Now, the greatest four digit no is 9999                            

divide the 9999 / 360                                                                

                 r = 279                                                                        

          sub  279 = r + 9999                                                                                    

                  r = 9999 - 279

                       = 9720

hence , the greatest no of four digit  which is exactly divisible by 15 , 24 , 36

are 9720
