Given numbers are 390, 657, 808, 178

The list of prime factors of all numbers are

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

Prime factors of 657 are 3 x 3 x 73

Prime factors of 808 are 2 x 2 x 2 x 101

Prime factors of 178 are 2 x 89

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

Given numbers are 390, 657, 808, 178

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

Apply this formula for all numbers.

Step1:

LCM(390, 657) = 85410

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

= 390 / 657

= 390

Step2:

LCM(3, 808) = 2424

GCD(3, 808) = ( 3 x 808 ) / 2424

= 3 / 808

= 3

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 390, 657, 808, 178 is 1
