Given numbers are 207, 679, 542, 780

The list of prime factors of all numbers are

Prime factors of 207 are 3 x 3 x 23

Prime factors of 679 are 7 x 97

Prime factors of 542 are 2 x 271

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

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

Given numbers are 207, 679, 542, 780

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

Apply this formula for all numbers.

Step1:

LCM(207, 679) = 140553

GCD(207, 679) = ( 207 x 679 ) / 140553

= 207 / 679

= 207

Step2:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 207, 679, 542, 780 is 1
