Two pairs: 1 and 26 2 and 13
its a factor with two pairs of the same number
The number 4 has two factor pairs. 1 x 4 and 2 x 2
1 and 14, 2 and 7
1 and 38 2 and 19
2 factor pairs
Factor pairs are just the factors of a number listed in a different way. The factors of 20 are 1, 2, 4, 5, 10, 20 The factor pairs of 20 are (20,1)(10,2)(5,4)
If you mean factor pairs then I know: Factor pairs and factors are both same things and for example this is a factor pair: 4x5, 6x5, 7x5. Factors or factor pairs is an equation that equals to a total: for example: factors of 20: 5x4, 4x5. BONUS: If one number has 2 or more factor pairs then that is a composite. If a number only has below and 2 that is a prime number.
1,2, 11, 22 The pairs are 1 & 22, 2&11 :)
These are the 16 factor pairs for the number 1,080:1080,1540,2360,3270,4216,5180,6135,8120,9108,1090,1272,1560,1854,2045,2440,2736,30
The factor pairs are all the factors of the number, just listed in pairs.
A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
