Dart int gcd()
Syntax & Examples

int.gcd() method

The `gcd` method in Dart returns the greatest common divisor of this integer and another integer.

Syntax of int.gcd()

The syntax of int.gcd() method is:

 int gcd(int other)

This gcd() method of int returns the greatest common divisor of this integer and other.

Parameters

ParameterOptional/RequiredDescription
otherrequiredThe other integer to find the greatest common divisor with.

Return Type

int.gcd() returns value of type int.


✐ Examples

1 Find the greatest common divisor of two numbers

In this example,

  1. We assign the values 24 and 36 to the integer variables num1 and num2 respectively.
  2. We find the greatest common divisor of num1 and num2 using the gcd() method.
  3. We print the result to standard output.

Dart Program

void main() {
  int num1 = 24;
  int num2 = 36;
  int greatestCommonDivisor = num1.gcd(num2);
  print('Greatest common divisor of $num1 and $num2: $greatestCommonDivisor');
}

Output

Greatest common divisor of 24 and 36: 12

2 Find the greatest common divisor of two numbers

In this example,

  1. We assign the values 56 and 72 to the integer variables num1 and num2 respectively.
  2. We find the greatest common divisor of num1 and num2 using the gcd() method.
  3. We print the result to standard output.

Dart Program

void main() {
  int num1 = 56;
  int num2 = 72;
  int greatestCommonDivisor = num1.gcd(num2);
  print('Greatest common divisor of $num1 and $num2: $greatestCommonDivisor');
}

Output

Greatest common divisor of 56 and 72: 8

3 Find the greatest common divisor of two numbers

In this example,

  1. We assign the values 105 and 140 to the integer variables num1 and num2 respectively.
  2. We find the greatest common divisor of num1 and num2 using the gcd() method.
  3. We print the result to standard output.

Dart Program

void main() {
  int num1 = 105;
  int num2 = 140;
  int greatestCommonDivisor = num1.gcd(num2);
  print('Greatest common divisor of $num1 and $num2: $greatestCommonDivisor');
}

Output

Greatest common divisor of 105 and 140: 35
