GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 166) = 65072
GCD(784, 166) = ( 784 x 166 ) / 65072
= 784 / 166
= 784
Step2:
LCM(2, 808) = 808
GCD(2, 808) = ( 2 x 808 ) / 808
= 2 / 808
= 2
Step3:
LCM(2, 249) = 498
GCD(2, 249) = ( 2 x 249 ) / 498
= 2 / 249
= 2
So, Greatest Common Divisor of 784, 166, 808, 249 is 1
