Given numbers are 781, 778, 431, 569

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

Apply this formula for all numbers.

Step1:

LCM(781, 778) = 607618

GCD(781, 778) = ( 781 x 778 ) / 607618

= 781 / 778

= 781

Step2:

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

= 1 / 431

= 1

Step3:

LCM(1, 569) = 569

GCD(1, 569) = ( 1 x 569 ) / 569

= 1 / 569

= 1

So, Greatest Common Divisor of 781, 778, 431, 569 is 1
