GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 817) = 177289
GCD(217, 817) = ( 217 x 817 ) / 177289
= 217 / 817
= 217
Step2:
LCM(1, 726) = 726
GCD(1, 726) = ( 1 x 726 ) / 726
= 1 / 726
= 1
Step3:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
So, Greatest Common Divisor of 217, 817, 726, 870 is 1
