Given numbers are 642, 764, 563, 191

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

Apply this formula for all numbers.

Step1:

LCM(642, 764) = 245244

GCD(642, 764) = ( 642 x 764 ) / 245244

= 642 / 764

= 642

Step2:

LCM(2, 563) = 1126

GCD(2, 563) = ( 2 x 563 ) / 1126

= 2 / 563

= 2

Step3:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

So, Greatest Common Divisor of 642, 764, 563, 191 is 1
