Given numbers are 780, 620, 139, 709

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 620 are 2 x 2 x 5 x 31

Prime factors of 139 are 139

Prime factors of 709 are 709

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

Given numbers are 780, 620, 139, 709

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

Apply this formula for all numbers.

Step1:

LCM(780, 620) = 24180

GCD(780, 620) = ( 780 x 620 ) / 24180

= 780 / 620

= 780

Step2:

LCM(20, 139) = 2780

GCD(20, 139) = ( 20 x 139 ) / 2780

= 20 / 139

= 20

Step3:

LCM(1, 709) = 709

GCD(1, 709) = ( 1 x 709 ) / 709

= 1 / 709

= 1

So, Greatest Common Divisor of 780, 620, 139, 709 is 1
