99 factors to [3 3 11] 121 factors to [11 11] Common factors [11] Answer is 11. ■
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
