GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 860) = 26660
GCD(155, 860) = ( 155 x 860 ) / 26660
= 155 / 860
= 155
Step2:
LCM(5, 355) = 355
GCD(5, 355) = ( 5 x 355 ) / 355
= 5 / 355
= 5
Step3:
LCM(5, 655) = 655
GCD(5, 655) = ( 5 x 655 ) / 655
= 5 / 655
= 5
So, Greatest Common Divisor of 155, 860, 355, 655 is 5
