GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(995, 720) = 143280
GCD(995, 720) = ( 995 x 720 ) / 143280
= 995 / 720
= 995
Step2:
LCM(5, 855) = 855
GCD(5, 855) = ( 5 x 855 ) / 855
= 5 / 855
= 5
Step3:
LCM(5, 685) = 685
GCD(5, 685) = ( 5 x 685 ) / 685
= 5 / 685
= 5
So, Greatest Common Divisor of 995, 720, 855, 685 is 5
