# Python | sympy.lcm() method

The function `lcm()` provides the direct way to compute Least Common Multiple for polynomials.That is, for polynomials f and g, it computes LCM.

```Syntax: sympy.lcm(f, g)

Return: LCM of given polynomials
```

Example #1:

 `# import sympy   ` `from` `sympy ``import` `*` `f ``=` `x ``*` `y``*``*``2` `+` `x``*``*``2` `*` `y ` `g ``=` `x``*``*``2` `*` `y``*``*``2` ` `  `# Using sympy.lcm() method  ` `gfg ``=` `lcm(f, g) ` ` `  `print``(gfg) `

Output:

```x**3*y**2 + x**2*y**3
```

Example #2:

 `# import sympy   ` `from` `sympy ``import` `*` `f ``=` `x ``*` `y ``/` `2` `+` `y``*``*``2` `g ``=` `3` `*` `x ``+` `6` `*` `y ` ` `  `# Using sympy.lcm() method  ` `gfg ``=` `lcm(f, g) ` ` `  `print``(gfg) `

Output:

```x*y + 2*y**2
```
