GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 109) = 70523
GCD(647, 109) = ( 647 x 109 ) / 70523
= 647 / 109
= 647
Step2:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
Step3:
LCM(1, 571) = 571
GCD(1, 571) = ( 1 x 571 ) / 571
= 1 / 571
= 1
So, Greatest Common Divisor of 647, 109, 688, 571 is 1
