No, you should continue checking for factor pairs even if you find a pair that repeats. A repeating pair indicates that the number is not a prime number, but there may be other factor pairs that have not been identified yet. It is important to exhaust all possible factor pairs to ensure that all factors of the number are identified accurately.
The factor pairs of 260 are (260,1), (130,2), (65,4), (52,5), (26,10), and (20,13)
1 x 61 is the only factor pair of 61.
55 = 1 x 55 55 = 5 x 11
There are 2 factor pairs of 55.55 = 1 x 5555 = 5 x 1155 = 1 x 5555 = 5 x 11(1,55)(5,11)
1x40, 2x20, 4x10, 5x8 are all the factor pairs of 40.
The factor pairs for 38 are (1, 19) and (2, 38).
The factor pairs of 26 are: 1 × 26 2 × 13
The factor pairs of 20 are pairs of numbers that can be multiplied together to give 20. The factor pairs of 20 are (1, 20), (2, 10), and (4, 5). These pairs represent all the possible combinations of numbers that can be multiplied to equal 20.
The GCF is 1. Anytime there are two consecutive integers, their GCF will be 1.
