Given numbers are 530, 808, 915, 491

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

Apply this formula for all numbers.

Step1:

LCM(530, 808) = 214120

GCD(530, 808) = ( 530 x 808 ) / 214120

= 530 / 808

= 530

Step2:

LCM(2, 915) = 1830

GCD(2, 915) = ( 2 x 915 ) / 1830

= 2 / 915

= 2

Step3:

LCM(1, 491) = 491

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

= 1 / 491

= 1

So, Greatest Common Divisor of 530, 808, 915, 491 is 1
