Given numbers are 239, 130, 510, 638

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

Apply this formula for all numbers.

Step1:

LCM(239, 130) = 31070

GCD(239, 130) = ( 239 x 130 ) / 31070

= 239 / 130

= 239

Step2:

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

= 1 / 510

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 239, 130, 510, 638 is 1
