Given numbers are 390, 713, 355, 808

The list of prime factors of all numbers are

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

Prime factors of 713 are 23 x 31

Prime factors of 355 are 5 x 71

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

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

Given numbers are 390, 713, 355, 808

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

Apply this formula for all numbers.

Step1:

LCM(390, 713) = 278070

GCD(390, 713) = ( 390 x 713 ) / 278070

= 390 / 713

= 390

Step2:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 390, 713, 355, 808 is 1
