GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 664) = 53784
GCD(648, 664) = ( 648 x 664 ) / 53784
= 648 / 664
= 648
Step2:
LCM(8, 606) = 2424
GCD(8, 606) = ( 8 x 606 ) / 2424
= 8 / 606
= 8
Step3:
LCM(2, 938) = 938
GCD(2, 938) = ( 2 x 938 ) / 938
= 2 / 938
= 2
So, Greatest Common Divisor of 648, 664, 606, 938 is 2
