Given numbers are 206, 580, 873, 690

The list of prime factors of all numbers are

Prime factors of 206 are 2 x 103

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 873 are 3 x 3 x 97

Prime factors of 690 are 2 x 3 x 5 x 23

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 206, 580, 873, 690

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(206, 580) = 59740

GCD(206, 580) = ( 206 x 580 ) / 59740

= 206 / 580

= 206

Step2:

LCM(2, 873) = 1746

GCD(2, 873) = ( 2 x 873 ) / 1746

= 2 / 873

= 2

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 206, 580, 873, 690 is 1
