Python | sympy.gcd() method Last Updated : 02 Aug, 2019 Comments Improve Suggest changes Like Article Like Report With the help of sympy.gcd() method, we can find the greatest common divisor of two numbers that is passed as a parameter in the sympy.gcd() method. Syntax : sympy.gcd(var1, var2) Return : Return value of greatest common divisor. Example #1 : In this example we can see that by using sympy.gcd() method, we are able to find the greatest common divisor of any two numbers that is passed as parameters. Python3 1=1 # import sympy from sympy import * # Using sympy.gcd() method gfg = gcd(6, 8) print(gfg) Output : 2 Example #2 : Python3 1=1 # import sympy from sympy import * # Using sympy.gcd() method gfg = gcd(177, 81) print(gfg) Output : 3 Comment More infoAdvertise with us Next Article Python | sympy.gcd() method J Jitender_1998 Follow Improve Article Tags : Python SymPy Practice Tags : python Similar Reads Python | sympy.igcd() method With the help of sympy.igcd() method, we can find the greatest common divisor of two nonnegative integer numbers that is passed as a parameter in the sympy.igcd() method.

Syntax: crt(m, v) Parameter: m - It denotes a list of integers. v - It denotes a list of integers. Returns: Returns a tuple of integers where the first element is the required result. Example #1: Python3 # 1 min read Python | sympy.core() method With the help of sympy.core() method, we can calculate the core_t(n) of a positive integer n. core(n, t) calculates the t-th power free part of n. If n’s prime factorization is : n = \prod_{i=1}^\omega p_i^{m_i} then core_t(n) = \prod_{i=1}^\omega p_i^{m_i \mod t} Syntax: core(n, t=2) Parameter: n - 1 min read Like
