11 and 31 and all the fives between numbers.
The prime numbers from 1 to 16 are 2, 3, 5, 7, 11, and 13.
3 + 13 = 16 5 + 11 = 16
11 + 3 + 2
11 and 5 13 and 3
11 and 5 13 and 3
Two: 11 and 13
Yes for example 5+11 = 16
12, 14, 15, 16, and 18 are composite numbers 11, 13, 17, and 19 are prime numbers
They are: 2 3 5 7 11 and 13
First express each of the numbers in prime factors:16 = 2411 = 11 (prime number)20 = 22 x 5Now, select the highest power for all prime numbers:24, 11, and 5 then multiply them all together. (16)(11)(5) = 880 is the LCMNote: 22 is not "counted" because it was a factor at a higher power in one of the other numbers. Take only the factor with the highest power.
