      To find the LCM of multiple numbers, you can list the multiples of each number and find the smallest number that appears in all lists. Alternatively, you can use the formula: LCM(a, b) = |a * b| / GCD(a, b). For example, to find the LCM of 7, 5, and 3, you can use the formula: LCM(7, 5, 3) = |7 * 5 * 3| / GCD(7, 5, 3) = 105 / 1 = 105.
