Given numbers are 813, 938, 390, 145

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 938 are 2 x 7 x 67

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

Prime factors of 145 are 5 x 29

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

Given numbers are 813, 938, 390, 145

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

Apply this formula for all numbers.

Step1:

LCM(813, 938) = 762594

GCD(813, 938) = ( 813 x 938 ) / 762594

= 813 / 938

= 813

Step2:

LCM(1, 390) = 390

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

= 1 / 390

= 1

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 813, 938, 390, 145 is 1
