GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 838) = 116482
GCD(278, 838) = ( 278 x 838 ) / 116482
= 278 / 838
= 278
Step2:
LCM(2, 798) = 798
GCD(2, 798) = ( 2 x 798 ) / 798
= 2 / 798
= 2
Step3:
LCM(2, 404) = 404
GCD(2, 404) = ( 2 x 404 ) / 404
= 2 / 404
= 2
So, Greatest Common Divisor of 278, 838, 798, 404 is 2
