GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(838, 916) = 383804
GCD(838, 916) = ( 838 x 916 ) / 383804
= 838 / 916
= 838
Step2:
LCM(2, 878) = 878
GCD(2, 878) = ( 2 x 878 ) / 878
= 2 / 878
= 2
Step3:
LCM(2, 289) = 578
GCD(2, 289) = ( 2 x 289 ) / 578
= 2 / 289
= 2
So, Greatest Common Divisor of 838, 916, 878, 289 is 1
