Given numbers are 517, 866, 197, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(517, 866) = 447722
GCD(517, 866) = ( 517 x 866 ) / 447722
= 517 / 866
= 517
Step2:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 517, 866, 197, 420 is 1
