True

Work Step by Step

The least common multiple of two numbers is the smallest number into which the original numbers divide. Therefore, we can look at a list of multiples of each number to find the LCM. 4- 4, 8, 12, 16, 20, 24, 28, 32, 36 9- 9, 18, 27, 36 We can see that 36 is the smallest number into which both 4 and 9 divide. Therefore, 36 is the LCM of 9 and 4.
