There are 2 factor pairs of 34:34 = 1 x 3434 = 2 x 17
1 x 85, 5 x 17, 17 x 5, 85 x 1
17 has one factor pair, 1 and 17.
1x40, 2x20, 4x10, 5x8 are all the factor pairs of 40.
17 is a prime number, so the only factor pair is 1 x 17.
The factor pairs of 34 are (1, 34) and (2, 17). This means that 1 multiplied by 34 equals 34, and 2 multiplied by 17 also equals 34. Since 34 is an even number, its only even factor pair is (2, 17).
1 x 17, 17 x 1 (17 is a prime number).
17 is prime. Its only factors are 1 and 17.
