Given numbers are 781, 274, 558, 810
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 274) = 213994
GCD(781, 274) = ( 781 x 274 ) / 213994
= 781 / 274
= 781
Step2:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 781, 274, 558, 810 is 1
