120
The Least Common Multiple (LCM) of 10, 20, 30, and 40 is the smallest number that is a multiple of all these numbers. To find the LCM, we first need to find the prime factors of each number: 10 = 2 x 5, 20 = 2^2 x 5, 30 = 2 x 3 x 5, and 40 = 2^3 x 5. Then, we take the highest power of each prime factor that appears in any of the numbers: 2^3 x 3 x 5 = 120. Therefore, the LCM of 10, 20, 30, and 40 is 120.
The least common multiple of 20 , 40 , 30 = 120
The LCM of all those numbers is 120 because it is the first number that 30, 40 and 20 divide into evenly.
