GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 868) = 868
GCD(217, 868) = ( 217 x 868 ) / 868
= 217 / 868
= 217
Step2:
LCM(217, 568) = 123256
GCD(217, 568) = ( 217 x 568 ) / 123256
= 217 / 568
= 217
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 217, 868, 568, 678 is 1
