Given numbers are 843, 338, 454, 639

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

Apply this formula for all numbers.

Step1:

LCM(843, 338) = 284934

GCD(843, 338) = ( 843 x 338 ) / 284934

= 843 / 338

= 843

Step2:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 843, 338, 454, 639 is 1
