Given numbers are 397, 978, 930, 529

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

Apply this formula for all numbers.

Step1:

LCM(397, 978) = 388266

GCD(397, 978) = ( 397 x 978 ) / 388266

= 397 / 978

= 397

Step2:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

Step3:

LCM(1, 529) = 529

GCD(1, 529) = ( 1 x 529 ) / 529

= 1 / 529

= 1

So, Greatest Common Divisor of 397, 978, 930, 529 is 1
