86 = (8 x 10) + (6 x 1)
2 x 43 = 86
prime factors of 86: 2, 43 prime factorization of 86: 2 x 43
86
The multiplication fact 1 x 85 = 85 with 1 and 85 adds to 86; The multiplication fact 2 x 84 = 168 with 2 and 84 adds to- 86; etc. But I don't quite think that is what you mean; I think you mean what are the factor pairs of 86: 1 x 86 & 2 x 43.
1 x 86, 2 x 43, 43 x 2, 86 x 1 = 86
10 x 8 + 3 x 2 ie 86
1, 2, 43, 86 (1 x 86, 2 x 43).
1 x 86, 2 x 43.
86 = (8 x 10) + (6 x 1)
1, 2, 43, 86: 1 x 86, 2 x 43.
2 x 43 = 86
If we restrict the discussion to integers (whole numbers), then there are only two possibilities: 1 x 86 2 x 43
2 x 43 = 86 2 x 7 x 11 = 154 The GCF is 2.
2 x 43 = 86
86 43 x 2
2 x 43 = 86
