Given numbers are 457, 390, 270, 495

The list of prime factors of all numbers are

Prime factors of 457 are 457

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

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 495 are 3 x 3 x 5 x 11

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

Given numbers are 457, 390, 270, 495

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

Apply this formula for all numbers.

Step1:

LCM(457, 390) = 178230

GCD(457, 390) = ( 457 x 390 ) / 178230

= 457 / 390

= 457

Step2:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

Step3:

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

= 1 / 495

= 1

So, Greatest Common Divisor of 457, 390, 270, 495 is 1
