Given numbers are 639, 279, 370, 563

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

Apply this formula for all numbers.

Step1:

LCM(639, 279) = 19809

GCD(639, 279) = ( 639 x 279 ) / 19809

= 639 / 279

= 639

Step2:

LCM(9, 370) = 3330

GCD(9, 370) = ( 9 x 370 ) / 3330

= 9 / 370

= 9

Step3:

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

= 1 / 563

= 1

So, Greatest Common Divisor of 639, 279, 370, 563 is 1
