Given numbers are 430, 405, 982, 872

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

Apply this formula for all numbers.

Step1:

LCM(430, 405) = 34830

GCD(430, 405) = ( 430 x 405 ) / 34830

= 430 / 405

= 430

Step2:

LCM(5, 982) = 4910

GCD(5, 982) = ( 5 x 982 ) / 4910

= 5 / 982

= 5

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 430, 405, 982, 872 is 1
