Given numbers are 538, 781, 780, 104

The list of prime factors of all numbers are

Prime factors of 538 are 2 x 269

Prime factors of 781 are 11 x 71

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

Prime factors of 104 are 2 x 2 x 2 x 13

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

Given numbers are 538, 781, 780, 104

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

Apply this formula for all numbers.

Step1:

LCM(538, 781) = 420178

GCD(538, 781) = ( 538 x 781 ) / 420178

= 538 / 781

= 538

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 104) = 104

GCD(1, 104) = ( 1 x 104 ) / 104

= 1 / 104

= 1

So, Greatest Common Divisor of 538, 781, 780, 104 is 1
