Given numbers are 780, 537, 642, 859

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 537 are 3 x 179

Prime factors of 642 are 2 x 3 x 107

Prime factors of 859 are 859

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

Given numbers are 780, 537, 642, 859

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

Apply this formula for all numbers.

Step1:

LCM(780, 537) = 139620

GCD(780, 537) = ( 780 x 537 ) / 139620

= 780 / 537

= 780

Step2:

LCM(3, 642) = 642

GCD(3, 642) = ( 3 x 642 ) / 642

= 3 / 642

= 3

Step3:

LCM(3, 859) = 2577

GCD(3, 859) = ( 3 x 859 ) / 2577

= 3 / 859

= 3

So, Greatest Common Divisor of 780, 537, 642, 859 is 1
