Given numbers are 781, 969, 489, 779

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

Apply this formula for all numbers.

Step1:

LCM(781, 969) = 756789

GCD(781, 969) = ( 781 x 969 ) / 756789

= 781 / 969

= 781

Step2:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

Step3:

LCM(1, 779) = 779

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

= 1 / 779

= 1

So, Greatest Common Divisor of 781, 969, 489, 779 is 1
