Given numbers are 719, 745, 809, 391

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

Apply this formula for all numbers.

Step1:

LCM(719, 745) = 535655

GCD(719, 745) = ( 719 x 745 ) / 535655

= 719 / 745

= 719

Step2:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 719, 745, 809, 391 is 1
