Given numbers are 428, 809, 779, 730

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

Apply this formula for all numbers.

Step1:

LCM(428, 809) = 346252

GCD(428, 809) = ( 428 x 809 ) / 346252

= 428 / 809

= 428

Step2:

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

= 1 / 779

= 1

Step3:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 428, 809, 779, 730 is 1
