Given numbers are 638, 394, 524, 285

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

Apply this formula for all numbers.

Step1:

LCM(638, 394) = 125686

GCD(638, 394) = ( 638 x 394 ) / 125686

= 638 / 394

= 638

Step2:

LCM(2, 524) = 524

GCD(2, 524) = ( 2 x 524 ) / 524

= 2 / 524

= 2

Step3:

LCM(2, 285) = 570

GCD(2, 285) = ( 2 x 285 ) / 570

= 2 / 285

= 2

So, Greatest Common Divisor of 638, 394, 524, 285 is 1
