Given numbers are 389, 780, 447, 658

The list of prime factors of all numbers are

Prime factors of 389 are 389

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 447 are 3 x 149

Prime factors of 658 are 2 x 7 x 47

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

Given numbers are 389, 780, 447, 658

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

Apply this formula for all numbers.

Step1:

LCM(389, 780) = 303420

GCD(389, 780) = ( 389 x 780 ) / 303420

= 389 / 780

= 389

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 389, 780, 447, 658 is 1
