Given numbers are 243, 783, 393, 547

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

Apply this formula for all numbers.

Step1:

LCM(243, 783) = 7047

GCD(243, 783) = ( 243 x 783 ) / 7047

= 243 / 783

= 243

Step2:

LCM(27, 393) = 3537

GCD(27, 393) = ( 27 x 393 ) / 3537

= 27 / 393

= 27

Step3:

LCM(3, 547) = 1641

GCD(3, 547) = ( 3 x 547 ) / 1641

= 3 / 547

= 3

So, Greatest Common Divisor of 243, 783, 393, 547 is 1
