Given numbers are 545, 266, 731, 390

The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 266 are 2 x 7 x 19

Prime factors of 731 are 17 x 43

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 545, 266, 731, 390

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

Apply this formula for all numbers.

Step1:

LCM(545, 266) = 144970

GCD(545, 266) = ( 545 x 266 ) / 144970

= 545 / 266

= 545

Step2:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 545, 266, 731, 390 is 1
