Given numbers are 243, 578, 605, 553

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

Apply this formula for all numbers.

Step1:

LCM(243, 578) = 140454

GCD(243, 578) = ( 243 x 578 ) / 140454

= 243 / 578

= 243

Step2:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

Step3:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

So, Greatest Common Divisor of 243, 578, 605, 553 is 1
