Given numbers are 457, 321, 540, 545

The list of prime factors of all numbers are

Prime factors of 457 are 457

Prime factors of 321 are 3 x 107

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 545 are 5 x 109

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

Given numbers are 457, 321, 540, 545

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

Apply this formula for all numbers.

Step1:

LCM(457, 321) = 146697

GCD(457, 321) = ( 457 x 321 ) / 146697

= 457 / 321

= 457

Step2:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 457, 321, 540, 545 is 1
