A number is divisible by 9 if the sum of its digits is divisible by 9. Thus, the number 99999 is divisible by 9 (the sum of its digits is 45, and it is clearly 11111 * 9), and because 99999 is the largest 5 digit number, it must be the largest 5 digit multiple of 9. 99999 is the greatest no divisible by 9.if u divide it u`ll get 11111.

You just need a 4 digit number divisible by 5x9 ie by 45, so 4500 will do.

There are at least 2. One is 2657205 the other is 3515625.You're right!There are 200,000 of them.The smallest one is 1,000,035 .The largest one is 9,999,990.You're welcome.Here are some more:4999995999999010555202944485etc.Any 7 digit number divisible by 45 works.

The lowest common multiple of 5 and 9 is 45 and 11 times 45 is 495 which is the greatest 3 digit number divisible by 5 and 9

It is easier to find the lowest common number, then getting the largest multiple of that that is under 10000. The LCM is 4680, x2 is 9360.

Count by 45. 45,90,135,180 so you have two choices.

90. All numbers divisible by 5 and 9 are multiples of their lowest common multiple. lcm(5, 9) = 45 → need an even two digit multiple of 45, which is 2 x 45 = 90.

The LCM always be the largest of the given numbers or a multiple of the largest number. The largest number given is 45, but 18 will not divide evenly into 45. The next multiple of 45 is 90 (2 x 45). Since 90 is divisible by both 5 and 18, then 90 is the LCM.
