Given numbers are 530, 781, 257, 188

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

Apply this formula for all numbers.

Step1:

LCM(530, 781) = 413930

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

= 530 / 781

= 530

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

= 1 / 188

= 1

So, Greatest Common Divisor of 530, 781, 257, 188 is 1
