Given numbers are 325, 678, 917, 780

The list of prime factors of all numbers are

Prime factors of 325 are 5 x 5 x 13

Prime factors of 678 are 2 x 3 x 113

Prime factors of 917 are 7 x 131

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

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

Given numbers are 325, 678, 917, 780

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

Apply this formula for all numbers.

Step1:

LCM(325, 678) = 220350

GCD(325, 678) = ( 325 x 678 ) / 220350

= 325 / 678

= 325

Step2:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 325, 678, 917, 780 is 1
