Given numbers are 790, 998, 784, 809

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(790, 998) = 394210

GCD(790, 998) = ( 790 x 998 ) / 394210

= 790 / 998

= 790

Step2:

LCM(2, 784) = 784

GCD(2, 784) = ( 2 x 784 ) / 784

= 2 / 784

= 2

Step3:

LCM(2, 809) = 1618

GCD(2, 809) = ( 2 x 809 ) / 1618

= 2 / 809

= 2

So, Greatest Common Divisor of 790, 998, 784, 809 is 1
