Given numbers are 639, 671, 847, 194

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

Apply this formula for all numbers.

Step1:

LCM(639, 671) = 428769

GCD(639, 671) = ( 639 x 671 ) / 428769

= 639 / 671

= 639

Step2:

LCM(1, 847) = 847

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

= 1 / 847

= 1

Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

So, Greatest Common Divisor of 639, 671, 847, 194 is 1
