Given numbers are 401, 601, 780, 858

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 601 are 601

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

Prime factors of 858 are 2 x 3 x 11 x 13

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

Given numbers are 401, 601, 780, 858

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

Apply this formula for all numbers.

Step1:

LCM(401, 601) = 241001

GCD(401, 601) = ( 401 x 601 ) / 241001

= 401 / 601

= 401

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 401, 601, 780, 858 is 1
