Given numbers are 639, 193, 126, 713

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

Apply this formula for all numbers.

Step1:

LCM(639, 193) = 123327

GCD(639, 193) = ( 639 x 193 ) / 123327

= 639 / 193

= 639

Step2:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

Step3:

LCM(1, 713) = 713

GCD(1, 713) = ( 1 x 713 ) / 713

= 1 / 713

= 1

So, Greatest Common Divisor of 639, 193, 126, 713 is 1
