Given numbers are 780, 417, 307, 698

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 417 are 3 x 139

Prime factors of 307 are 307

Prime factors of 698 are 2 x 349

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

Given numbers are 780, 417, 307, 698

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

Apply this formula for all numbers.

Step1:

LCM(780, 417) = 108420

GCD(780, 417) = ( 780 x 417 ) / 108420

= 780 / 417

= 780

Step2:

LCM(3, 307) = 921

GCD(3, 307) = ( 3 x 307 ) / 921

= 3 / 307

= 3

Step3:

LCM(1, 698) = 698

GCD(1, 698) = ( 1 x 698 ) / 698

= 1 / 698

= 1

So, Greatest Common Divisor of 780, 417, 307, 698 is 1
