Given numbers are 740, 728, 351, 390

The list of prime factors of all numbers are

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 351 are 3 x 3 x 3 x 13

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

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

Given numbers are 740, 728, 351, 390

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

Apply this formula for all numbers.

Step1:

LCM(740, 728) = 134680

GCD(740, 728) = ( 740 x 728 ) / 134680

= 740 / 728

= 740

Step2:

LCM(4, 351) = 1404

GCD(4, 351) = ( 4 x 351 ) / 1404

= 4 / 351

= 4

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 740, 728, 351, 390 is 1
