Given numbers are 643, 644, 582, 446

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 582 are 2 x 3 x 97

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 643, 644, 582, 446

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

Apply this formula for all numbers.

Step1:

LCM(643, 644) = 414092

GCD(643, 644) = ( 643 x 644 ) / 414092

= 643 / 644

= 643

Step2:

LCM(1, 582) = 582

GCD(1, 582) = ( 1 x 582 ) / 582

= 1 / 582

= 1

Step3:

LCM(1, 446) = 446

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

= 1 / 446

= 1

So, Greatest Common Divisor of 643, 644, 582, 446 is 1
