A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 55 are 1, 5, 11, and 55. The factors of 121 are 1, 11, and 121. The factors of 143 are 1, 11, 13, and 143. The common factors are 1 and 11. Therefore, the greatest common factor is 11.
