Given numbers are 530, 977, 241, 645

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

Apply this formula for all numbers.

Step1:

LCM(530, 977) = 517810

GCD(530, 977) = ( 530 x 977 ) / 517810

= 530 / 977

= 530

Step2:

LCM(1, 241) = 241

GCD(1, 241) = ( 1 x 241 ) / 241

= 1 / 241

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 530, 977, 241, 645 is 1
