Given numbers are 506, 690, 243, 605

The list of prime factors of all numbers are

Prime factors of 506 are 2 x 11 x 23

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 605 are 5 x 11 x 11

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 506, 690, 243, 605

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

Apply this formula for all numbers.

Step1:

LCM(506, 690) = 7590

GCD(506, 690) = ( 506 x 690 ) / 7590

= 506 / 690

= 506

Step2:

LCM(46, 243) = 11178

GCD(46, 243) = ( 46 x 243 ) / 11178

= 46 / 243

= 46

Step3:

LCM(1, 605) = 605

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

= 1 / 605

= 1

So, Greatest Common Divisor of 506, 690, 243, 605 is 1
