Given numbers are 657, 390, 406, 585

The list of prime factors of all numbers are

Prime factors of 657 are 3 x 3 x 73

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

Prime factors of 406 are 2 x 7 x 29

Prime factors of 585 are 3 x 3 x 5 x 13

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

Given numbers are 657, 390, 406, 585

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

Apply this formula for all numbers.

Step1:

LCM(657, 390) = 85410

GCD(657, 390) = ( 657 x 390 ) / 85410

= 657 / 390

= 657

Step2:

LCM(3, 406) = 1218

GCD(3, 406) = ( 3 x 406 ) / 1218

= 3 / 406

= 3

Step3:

LCM(1, 585) = 585

GCD(1, 585) = ( 1 x 585 ) / 585

= 1 / 585

= 1

So, Greatest Common Divisor of 657, 390, 406, 585 is 1
