Given numbers are 816, 639, 839, 343

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

Apply this formula for all numbers.

Step1:

LCM(816, 639) = 173808

GCD(816, 639) = ( 816 x 639 ) / 173808

= 816 / 639

= 816

Step2:

LCM(3, 839) = 2517

GCD(3, 839) = ( 3 x 839 ) / 2517

= 3 / 839

= 3

Step3:

LCM(1, 343) = 343

GCD(1, 343) = ( 1 x 343 ) / 343

= 1 / 343

= 1

So, Greatest Common Divisor of 816, 639, 839, 343 is 1
