Given numbers are 252, 556, 191, 643

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

Apply this formula for all numbers.

Step1:

LCM(252, 556) = 35028

GCD(252, 556) = ( 252 x 556 ) / 35028

= 252 / 556

= 252

Step2:

LCM(4, 191) = 764

GCD(4, 191) = ( 4 x 191 ) / 764

= 4 / 191

= 4

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 252, 556, 191, 643 is 1
