Given numbers are 644, 425, 471, 303

The list of prime factors of all numbers are

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

Prime factors of 425 are 5 x 5 x 17

Prime factors of 471 are 3 x 157

Prime factors of 303 are 3 x 101

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

Given numbers are 644, 425, 471, 303

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

Apply this formula for all numbers.

Step1:

LCM(644, 425) = 273700

GCD(644, 425) = ( 644 x 425 ) / 273700

= 644 / 425

= 644

Step2:

LCM(1, 471) = 471

GCD(1, 471) = ( 1 x 471 ) / 471

= 1 / 471

= 1

Step3:

LCM(1, 303) = 303

GCD(1, 303) = ( 1 x 303 ) / 303

= 1 / 303

= 1

So, Greatest Common Divisor of 644, 425, 471, 303 is 1
