Given numbers are 781, 530, 669

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

Apply this formula for all numbers.

Step1:

LCM(781, 530) = 413930

GCD(781, 530) = ( 781 x 530 ) / 413930

= 781 / 530

= 781

Step2:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 781, 530, 669 is 1
