Given numbers are 909, 603, 985, 243

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

Apply this formula for all numbers.

Step1:

LCM(909, 603) = 60903

GCD(909, 603) = ( 909 x 603 ) / 60903

= 909 / 603

= 909

Step2:

LCM(9, 985) = 8865

GCD(9, 985) = ( 9 x 985 ) / 8865

= 9 / 985

= 9

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 909, 603, 985, 243 is 1
