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

Apply this formula for all numbers.

Step1:

LCM(530, 845) = 89570

GCD(530, 845) = ( 530 x 845 ) / 89570

= 530 / 845

= 530

Step2:

LCM(5, 685) = 685

GCD(5, 685) = ( 5 x 685 ) / 685

= 5 / 685

= 5

Step3:

LCM(5, 970) = 970

GCD(5, 970) = ( 5 x 970 ) / 970

= 5 / 970

= 5

So, Greatest Common Divisor of 530, 845, 685, 970 is 5
