3 and 13 or 5 and 11
11 + 3 + 2
16 prime numbers
Every number has a factor pair of 1 and itself. Prime numbers have that as their only factor pair. Composite numbers have additional factor pairs. 7 = 1 x 7 9 = 1 x 9 16 = 1 x 16 and others 21 = 1 x 21 and others
The GCF is a single number so there cannot be any pair of numbers in the answer.
13+3=16
11 and 5 13 and 3
The prime factorization of 32 is: 2 x 16 2 x 2 x 8 2 x 2 x 2 x4 2 x 2 x 2 x 2 x 2. There is not a pair of prime numbers that make 32.
2x2x2x2=16
3 and 13 or 5 and 11
11 + 3 + 2
The prime numbers under 16 are 2,3,5,7,11 & 13.
16 prime numbers
The only prime factor of 16 is 2.
Joint prime numbers, or coprimes, as they are better known, are numbers which do not share any factor in common (other than 1). The numbers may not themselves be prime. Any pair of successive integers must be coprime even if one or both of them may be composite. For example, 15 and 16.
16 - 9 = 7.
Every number has a factor pair of 1 and itself. Prime numbers have that as their only factor pair. Composite numbers have additional factor pairs. 7 = 1 x 7 9 = 1 x 9 16 = 1 x 16 and others 21 = 1 x 21 and others
