Given numbers are 818, 621, 321, 983

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

Apply this formula for all numbers.

Step1:

LCM(818, 621) = 507978

GCD(818, 621) = ( 818 x 621 ) / 507978

= 818 / 621

= 818

Step2:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

Step3:

LCM(1, 983) = 983

GCD(1, 983) = ( 1 x 983 ) / 983

= 1 / 983

= 1

So, Greatest Common Divisor of 818, 621, 321, 983 is 1
