Given numbers are 623, 407, 921, 664

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 407 are 11 x 37

Prime factors of 921 are 3 x 307

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 623, 407, 921, 664

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

Apply this formula for all numbers.

Step1:

LCM(623, 407) = 253561

GCD(623, 407) = ( 623 x 407 ) / 253561

= 623 / 407

= 623

Step2:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 623, 407, 921, 664 is 1
