Given numbers are 818, 454, 481, 643

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

Apply this formula for all numbers.

Step1:

LCM(818, 454) = 185686

GCD(818, 454) = ( 818 x 454 ) / 185686

= 818 / 454

= 818

Step2:

LCM(2, 481) = 962

GCD(2, 481) = ( 2 x 481 ) / 962

= 2 / 481

= 2

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 818, 454, 481, 643 is 1
