Given numbers are 781, 394, 370, 530

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

Apply this formula for all numbers.

Step1:

LCM(781, 394) = 307714

GCD(781, 394) = ( 781 x 394 ) / 307714

= 781 / 394

= 781

Step2:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

Step3:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

So, Greatest Common Divisor of 781, 394, 370, 530 is 1
