Answer 1

999972........the largest 6 digit number which is divisible by 12, 24 and 36
LCM of 12 24 and 36 is 36
therefore when we divide larget six digit no. by 36
999999/36 we get 27 as remainder
therefore the largest 6 digit number which is divisible by 12, 24 and 36
999999-27=999972

Answer 2

hye

=============================

aim : Find the largest 6 digit number which is divisible by 12, 24 and 36

largest 6 digit number = 999999

now let us find the lcm of 12,24 and 36

=>12 = 2*2 * 3  

=>   24 = 2*2*2*3 

=>
    36 = 2*2 *3*3

common factors = 2*2*2*3*3

                             = 72

now lets us divide 999999/72

=>13888.875

let us round of 13888.875 to the next least hunderd


so we write 13888 [approx]

now,

=>13888* 72

=> 999936


hence the answer is 99936
