The are 1 and 11
The GCF is 11.
The greatest common factor (GCF) of 55 and 66 is 11. To find the GCF, we can list the factors of each number: the factors of 55 are 1, 5, 11, and 55, while the factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66. The highest factor that appears in both lists is 11.
You need at least two numbers to find common factors. If that's 55 and 66, the common factors are 1 and 11.
gcf(55, 66) = 11.
The Least Common Multiple (LCM) of 55 and 66 is 330.
The GCF of 55 and 66 is 11
The least common multiple of 66 , 55 = 330
A common denominator, though not the least one, is 66*55 = 3630.
