Given numbers are 639, 203, 886, 648

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

Apply this formula for all numbers.

Step1:

LCM(639, 203) = 129717

GCD(639, 203) = ( 639 x 203 ) / 129717

= 639 / 203

= 639

Step2:

LCM(1, 886) = 886

GCD(1, 886) = ( 1 x 886 ) / 886

= 1 / 886

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 639, 203, 886, 648 is 1
