Given numbers are 639, 563, 819, 670

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

Apply this formula for all numbers.

Step1:

LCM(639, 563) = 359757

GCD(639, 563) = ( 639 x 563 ) / 359757

= 639 / 563

= 639

Step2:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 639, 563, 819, 670 is 1
