Given numbers are 345, 657, 380, 386

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 657 are 3 x 3 x 73

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 386 are 2 x 193

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

Given numbers are 345, 657, 380, 386

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

Apply this formula for all numbers.

Step1:

LCM(345, 657) = 75555

GCD(345, 657) = ( 345 x 657 ) / 75555

= 345 / 657

= 345

Step2:

LCM(3, 380) = 1140

GCD(3, 380) = ( 3 x 380 ) / 1140

= 3 / 380

= 3

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 345, 657, 380, 386 is 1
