The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 780, 620, 795, 799
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, 795) = 3180
GCD(20, 795) = ( 20 x 795 ) / 3180
= 20 / 795
= 20
Step3:
LCM(5, 799) = 3995
GCD(5, 799) = ( 5 x 799 ) / 3995
= 5 / 799
= 5
So, Greatest Common Divisor of 780, 620, 795, 799 is 1
