What two numbers add up to 18?
9 9
What is the first multiple of 9 that contains all even numbers?
288. All multiples of 9 will have digits that add to a multiple of 9. To get a multiple of 9 to be all even, you need to get them to add to 18, since no set of even numbers will add up to 9. 288 is the lowest multiple of 9 to be able to add to 18. ■

What is the highest common multiple of 121827?
There is no highest common multiple - for whatever value you come up with, I can always add the lowest common multiple and get another, even higher common multiple.There is the:``highest common factor'' (hcf) which is the highest whole number that divides exactly into two or more numbers; and``lowest common multiple'' (lcm) which is the smallest whole number into which two or more numbers all divide exactly.By itself 121827 cannot have a common anything as that requires two or more numbers; however, I suspect that there are spaces missing and your list of numbers is actually {12, 18, 27}, givinghcf(12, 18, 27) = 3lcm(12, 18, 27) = 108If neither, please re-enter your question with a proper number list and hcf/lcm requirement.
What two numbers multiply to get 90 and add up to 23?

What are two consecutive number that add up to the number 35?
The numbers are 17 and 18.
What are the two numbers if they are relatively prime and their sum is 20 and their least common multiple is 99?
If the two numbers are relatively prime, their least common multiple is their product. The prime factors of 99 are 3, 3, and 11. Since the two numbers are relatively prime, the possibilities are 9 and 11 or 1 and 99. The pair of 9 and 11 add up to 20 and their least common multiple is 99. So, 9 and 11 are the two numbers.
