Given numbers are 103, 645, 333, 643

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

Apply this formula for all numbers.

Step1:

LCM(103, 645) = 66435

GCD(103, 645) = ( 103 x 645 ) / 66435

= 103 / 645

= 103

Step2:

LCM(1, 333) = 333

GCD(1, 333) = ( 1 x 333 ) / 333

= 1 / 333

= 1

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 103, 645, 333, 643 is 1
