Given numbers are 243, 663, 691, 481

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

Apply this formula for all numbers.

Step1:

LCM(243, 663) = 53703

GCD(243, 663) = ( 243 x 663 ) / 53703

= 243 / 663

= 243

Step2:

LCM(3, 691) = 2073

GCD(3, 691) = ( 3 x 691 ) / 2073

= 3 / 691

= 3

Step3:

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

= 1 / 481

= 1

So, Greatest Common Divisor of 243, 663, 691, 481 is 1
