Given numbers are 639, 834, 103, 455

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

Apply this formula for all numbers.

Step1:

LCM(639, 834) = 177642

GCD(639, 834) = ( 639 x 834 ) / 177642

= 639 / 834

= 639

Step2:

LCM(3, 103) = 309

GCD(3, 103) = ( 3 x 103 ) / 309

= 3 / 103

= 3

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 639, 834, 103, 455 is 1
