Given numbers are 412, 745, 780, 819

The list of prime factors of all numbers are

Prime factors of 412 are 2 x 2 x 103

Prime factors of 745 are 5 x 149

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

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 412, 745, 780, 819

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

Apply this formula for all numbers.

Step1:

LCM(412, 745) = 306940

GCD(412, 745) = ( 412 x 745 ) / 306940

= 412 / 745

= 412

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 412, 745, 780, 819 is 1
