Given numbers are 442, 657, 819, 644

The list of prime factors of all numbers are

Prime factors of 442 are 2 x 13 x 17

Prime factors of 657 are 3 x 3 x 73

Prime factors of 819 are 3 x 3 x 7 x 13

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

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

Given numbers are 442, 657, 819, 644

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

Apply this formula for all numbers.

Step1:

LCM(442, 657) = 290394

GCD(442, 657) = ( 442 x 657 ) / 290394

= 442 / 657

= 442

Step2:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 442, 657, 819, 644 is 1
