Given numbers are 130, 809, 539, 491

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

Apply this formula for all numbers.

Step1:

LCM(130, 809) = 105170

GCD(130, 809) = ( 130 x 809 ) / 105170

= 130 / 809

= 130

Step2:

LCM(1, 539) = 539

GCD(1, 539) = ( 1 x 539 ) / 539

= 1 / 539

= 1

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 130, 809, 539, 491 is 1
