Given numbers are 139, 780, 158, 611

The list of prime factors of all numbers are

Prime factors of 139 are 139

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

Prime factors of 158 are 2 x 79

Prime factors of 611 are 13 x 47

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

Given numbers are 139, 780, 158, 611

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

Apply this formula for all numbers.

Step1:

LCM(139, 780) = 108420

GCD(139, 780) = ( 139 x 780 ) / 108420

= 139 / 780

= 139

Step2:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

Step3:

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

= 1 / 611

= 1

So, Greatest Common Divisor of 139, 780, 158, 611 is 1
