Given numbers are 780, 559, 689, 206

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 559 are 13 x 43

Prime factors of 689 are 13 x 53

Prime factors of 206 are 2 x 103

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

Given numbers are 780, 559, 689, 206

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

Apply this formula for all numbers.

Step1:

LCM(780, 559) = 33540

GCD(780, 559) = ( 780 x 559 ) / 33540

= 780 / 559

= 780

Step2:

LCM(13, 689) = 689

GCD(13, 689) = ( 13 x 689 ) / 689

= 13 / 689

= 13

Step3:

LCM(13, 206) = 2678

GCD(13, 206) = ( 13 x 206 ) / 2678

= 13 / 206

= 13

So, Greatest Common Divisor of 780, 559, 689, 206 is 1
