The common factors of 99 and 121 are the numbers that can evenly divide both 99 and 121 without leaving a remainder. The factors of 99 are 1, 3, 9, 11, 33, and 99. The factors of 121 are 1, 11, and 121. Therefore, the only common factor of 99 and 121 is 1.
To find the least common multiple you first need to identify the prime factors of the two numbers. In this case: 99 = 3x3x11 121 = 11x11 The next step is to identify any common factors and discard the duplicate. In this case, both numbers have 11 as a common factor, so we can discard one, leaving us with 3, 3, 11 and 11. Multiply these together to find the LCM: 3x3x11x11=1,089 Thus the least common multiple of 99 and 121 is 1,089
Factor the numerator and denominator and cancel out like factors: 121/99 = (11*11)/(9*11) = 11/9
