Given numbers are 685, 521, 527, 424

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

Apply this formula for all numbers.

Step1:

LCM(685, 521) = 356885

GCD(685, 521) = ( 685 x 521 ) / 356885

= 685 / 521

= 685

Step2:

LCM(1, 527) = 527

GCD(1, 527) = ( 1 x 527 ) / 527

= 1 / 527

= 1

Step3:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

So, Greatest Common Divisor of 685, 521, 527, 424 is 1
