Given numbers are 621, 762, 805, 401

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 762 are 2 x 3 x 127

Prime factors of 805 are 5 x 7 x 23

Prime factors of 401 are 401

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

Given numbers are 621, 762, 805, 401

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

Apply this formula for all numbers.

Step1:

LCM(621, 762) = 157734

GCD(621, 762) = ( 621 x 762 ) / 157734

= 621 / 762

= 621

Step2:

LCM(3, 805) = 2415

GCD(3, 805) = ( 3 x 805 ) / 2415

= 3 / 805

= 3

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 621, 762, 805, 401 is 1
