Given numbers are 855, 605, 983, 243

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

Apply this formula for all numbers.

Step1:

LCM(855, 605) = 103455

GCD(855, 605) = ( 855 x 605 ) / 103455

= 855 / 605

= 855

Step2:

LCM(5, 983) = 4915

GCD(5, 983) = ( 5 x 983 ) / 4915

= 5 / 983

= 5

Step3:

LCM(1, 243) = 243

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

= 1 / 243

= 1

So, Greatest Common Divisor of 855, 605, 983, 243 is 1
