Given numbers are 243, 308, 840, 557

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

Apply this formula for all numbers.

Step1:

LCM(243, 308) = 74844

GCD(243, 308) = ( 243 x 308 ) / 74844

= 243 / 308

= 243

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 557) = 557

GCD(1, 557) = ( 1 x 557 ) / 557

= 1 / 557

= 1

So, Greatest Common Divisor of 243, 308, 840, 557 is 1
