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

Apply this formula for all numbers.

Step1:

LCM(619, 809) = 500771

GCD(619, 809) = ( 619 x 809 ) / 500771

= 619 / 809

= 619

Step2:

LCM(1, 876) = 876

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

= 1 / 876

= 1

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 619, 809, 876, 781 is 1
