GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(708, 784) = 138768
GCD(708, 784) = ( 708 x 784 ) / 138768
= 708 / 784
= 708
Step2:
LCM(4, 664) = 664
GCD(4, 664) = ( 4 x 664 ) / 664
= 4 / 664
= 4
Step3:
LCM(4, 838) = 1676
GCD(4, 838) = ( 4 x 838 ) / 1676
= 4 / 838
= 4
So, Greatest Common Divisor of 708, 784, 664, 838 is 2
