GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 920) = 181240
GCD(394, 920) = ( 394 x 920 ) / 181240
= 394 / 920
= 394
Step2:
LCM(2, 139) = 278
GCD(2, 139) = ( 2 x 139 ) / 278
= 2 / 139
= 2
Step3:
LCM(1, 938) = 938
GCD(1, 938) = ( 1 x 938 ) / 938
= 1 / 938
= 1
So, Greatest Common Divisor of 394, 920, 139, 938 is 1
