Given numbers are 621, 671, 864, 446

The list of prime factors of all numbers are

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

Prime factors of 671 are 11 x 61

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 446 are 2 x 223

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

Given numbers are 621, 671, 864, 446

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

Apply this formula for all numbers.

Step1:

LCM(621, 671) = 416691

GCD(621, 671) = ( 621 x 671 ) / 416691

= 621 / 671

= 621

Step2:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

Step3:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

So, Greatest Common Divisor of 621, 671, 864, 446 is 1
