The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 130, 434, 64, 809

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

Apply this formula for all numbers.

Step1:

LCM(130, 434) = 28210

GCD(130, 434) = ( 130 x 434 ) / 28210

= 130 / 434

= 130

Step2:

LCM(2, 64) = 64

GCD(2, 64) = ( 2 x 64 ) / 64

= 2 / 64

= 2

Step3:

LCM(2, 809) = 1618

GCD(2, 809) = ( 2 x 809 ) / 1618

= 2 / 809

= 2

So, Greatest Common Divisor of 130, 434, 64, 809 is 1
