Python math.gcd()
math.gcd(*integers) function returns the Greatest Common Divisor (GCD) of the integers passed as arguments.
Syntax
The syntax to call gcd() function is
math.gcd(*integers)
where
Parameter | Required | Description |
---|---|---|
*integers | No | None, one or multiple integer values. |
If no integer value is passed as argument to gcd(), then the return value is 0.
If only one integer is passed to gcd(), then then same value is returned as GCD.
If any non-integral value is passed as argument to gcd(), then the function raises TypeError.
Examples
GCD of two integers: 10 and 25.
Python Program
import math
result = math.gcd(10, 25)
print('gcd() :', result)
Run Output
gcd() : 5
GCD of one integer value.
Python Program
import math
result = math.gcd(25)
print('gcd() :', result)
Run Output
gcd() : 25
GCD of arguments containing floating point values.
Python Program
import math
result = math.gcd(25.5, 2.6)
print('gcd() :', result)
Run Output
TypeError: 'float' object cannot be interpreted as an integer
