Given numbers are 243, 903, 764, 657

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

Apply this formula for all numbers.

Step1:

LCM(243, 903) = 73143

GCD(243, 903) = ( 243 x 903 ) / 73143

= 243 / 903

= 243

Step2:

LCM(3, 764) = 2292

GCD(3, 764) = ( 3 x 764 ) / 2292

= 3 / 764

= 3

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 243, 903, 764, 657 is 1
