Given numbers are 780, 939, 651, 409

The list of prime factors of all numbers are

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

Prime factors of 939 are 3 x 313

Prime factors of 651 are 3 x 7 x 31

Prime factors of 409 are 409

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

Given numbers are 780, 939, 651, 409

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

Apply this formula for all numbers.

Step1:

LCM(780, 939) = 244140

GCD(780, 939) = ( 780 x 939 ) / 244140

= 780 / 939

= 780

Step2:

LCM(3, 651) = 651

GCD(3, 651) = ( 3 x 651 ) / 651

= 3 / 651

= 3

Step3:

LCM(3, 409) = 1227

GCD(3, 409) = ( 3 x 409 ) / 1227

= 3 / 409

= 3

So, Greatest Common Divisor of 780, 939, 651, 409 is 1
