Given numbers are 781, 643, 876, 535

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

Apply this formula for all numbers.

Step1:

LCM(781, 643) = 502183

GCD(781, 643) = ( 781 x 643 ) / 502183

= 781 / 643

= 781

Step2:

LCM(1, 876) = 876

GCD(1, 876) = ( 1 x 876 ) / 876

= 1 / 876

= 1

Step3:

LCM(1, 535) = 535

GCD(1, 535) = ( 1 x 535 ) / 535

= 1 / 535

= 1

So, Greatest Common Divisor of 781, 643, 876, 535 is 1
