From Python 3.9, the Math module has added a new function lcm function that calculates the minimum common multiple. In version 3.9, the lcm function can be used to quickly obtain the minimum common multiple of 2 integers, as shown in the following figure 1.

2 integers minimum common multiple

In version 3.9, the lcm function can be used to quickly obtain the minimum common multiple of 2 integers, as shown in the following figure 1.

Example 1

. In version 3.8 and previous versions, the gcd function needs to be used, as shown in the following figure 2.

Example 2

In example 2, a function is defined, and the return value of the function is the minimum common multiple of the variables X and Y. After substituting 6 and 4 into the custom function, the minimum common multiple is 12. It should be noted that if you use "/" in a custom function, you will generate a floating point decimal (flot), so you use the "//" (divided) operator.

In version 3.9, the lcm function also supports the calculation of more than 3 integers. As shown in Figure 3 below.

Example 3

In version 3.8, you need to use the gcd function and customize the function. Example 4 below.

Example 4

List object features minimum common multiple

When you find the minimum common multiple for the features in the list object, you must add "*" before the parameter. As shown in Figure 5,
