import "math/big" a := big.NewInt(12345678901234567890) b := big.NewInt(98765432109876543210) gcd := big.NewInt(0) gcd.GCD(nil, nil, a, b)This example demonstrates how to compute the greatest common divisor (GCD) of two big Ints using the GCD function from the math/big package. We create two big Int variables and initialize them with the values of the numbers we want to compute the GCD for. We then create a third big Int variable and use the GCD function to compute the GCD of the first two variables and set the result to the third variable. The first two arguments to the GCD function in this case are nil, indicating that we want the function to use the default GCD algorithm. In conclusion, the math/big package is a powerful tool for dealing with large numbers in Go. Its functions and methods are versatile and can be used in various applications that involve integer arithmetic.
