Given numbers are 444, 807, 623, 640

The list of prime factors of all numbers are

Prime factors of 444 are 2 x 2 x 3 x 37

Prime factors of 807 are 3 x 269

Prime factors of 623 are 7 x 89

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 444, 807, 623, 640

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

Apply this formula for all numbers.

Step1:

LCM(444, 807) = 119436

GCD(444, 807) = ( 444 x 807 ) / 119436

= 444 / 807

= 444

Step2:

LCM(3, 623) = 1869

GCD(3, 623) = ( 3 x 623 ) / 1869

= 3 / 623

= 3

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 444, 807, 623, 640 is 1
