Given numbers are 194, 425, 437, 645

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

Apply this formula for all numbers.

Step1:

LCM(194, 425) = 82450

GCD(194, 425) = ( 194 x 425 ) / 82450

= 194 / 425

= 194

Step2:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 194, 425, 437, 645 is 1
