Given numbers are 243, 672, 121, 552

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

Apply this formula for all numbers.

Step1:

LCM(243, 672) = 54432

GCD(243, 672) = ( 243 x 672 ) / 54432

= 243 / 672

= 243

Step2:

LCM(3, 121) = 363

GCD(3, 121) = ( 3 x 121 ) / 363

= 3 / 121

= 3

Step3:

LCM(1, 552) = 552

GCD(1, 552) = ( 1 x 552 ) / 552

= 1 / 552

= 1

So, Greatest Common Divisor of 243, 672, 121, 552 is 1
