Given numbers are 401, 780, 320, 104

The list of prime factors of all numbers are

Prime factors of 401 are 401

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

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 104 are 2 x 2 x 2 x 13

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

Given numbers are 401, 780, 320, 104

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

Apply this formula for all numbers.

Step1:

LCM(401, 780) = 312780

GCD(401, 780) = ( 401 x 780 ) / 312780

= 401 / 780

= 401

Step2:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

Step3:

LCM(1, 104) = 104

GCD(1, 104) = ( 1 x 104 ) / 104

= 1 / 104

= 1

So, Greatest Common Divisor of 401, 780, 320, 104 is 1
