Given numbers are 639, 178, 847, 326

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

Apply this formula for all numbers.

Step1:

LCM(639, 178) = 113742

GCD(639, 178) = ( 639 x 178 ) / 113742

= 639 / 178

= 639

Step2:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

Step3:

LCM(1, 326) = 326

GCD(1, 326) = ( 1 x 326 ) / 326

= 1 / 326

= 1

So, Greatest Common Divisor of 639, 178, 847, 326 is 1
