Given numbers are 638, 574, 943, 509

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

Apply this formula for all numbers.

Step1:

LCM(638, 574) = 183106

GCD(638, 574) = ( 638 x 574 ) / 183106

= 638 / 574

= 638

Step2:

LCM(2, 943) = 1886

GCD(2, 943) = ( 2 x 943 ) / 1886

= 2 / 943

= 2

Step3:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

So, Greatest Common Divisor of 638, 574, 943, 509 is 1
