The number 10 can be the product of 2 and 5, 1 and 10. This means that 10 has 4 factors. :]
1,2,3,6,9,18
10^18= 10,000,000,000,000,000,000 which is ten quintillion
18 is 10 greater than 8.

13 and 19 aren't composite. 1,2,5,10 1,13 1,2,3,6,9,18 1,19
The greatest common multiple of 10 and 18 is infinite.However, I suspect you want either:the greatest common factor of 10 and 18 which is the largest number which divides both 10 and 18 and is 2; orthe lowest common multiple of 10 and 18 which is smallest number into which both 10 and 18 divide (ie the smallest number which is a multiple of both 10 and 18) and is 90
195/18 = 10-15/18 = 10-5/6

10:18 or 5:9 (simplified)
10 and 11/18
An atom of oxygen-18 has 10 neutrons. This is calculated by subtracting the atomic number (8) from the atomic mass (18).

He used to be number 18, but now he is number 10.
