Given numbers are 530, 986, 890, 809

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

Apply this formula for all numbers.

Step1:

LCM(530, 986) = 261290

GCD(530, 986) = ( 530 x 986 ) / 261290

= 530 / 986

= 530

Step2:

LCM(2, 890) = 890

GCD(2, 890) = ( 2 x 890 ) / 890

= 2 / 890

= 2

Step3:

LCM(2, 809) = 1618

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

= 2 / 809

= 2

So, Greatest Common Divisor of 530, 986, 890, 809 is 1
