Given numbers are 781, 397, 877, 189

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

Apply this formula for all numbers.

Step1:

LCM(781, 397) = 310057

GCD(781, 397) = ( 781 x 397 ) / 310057

= 781 / 397

= 781

Step2:

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

= 1 / 877

= 1

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 781, 397, 877, 189 is 1
