Given numbers are 973, 372, 644, 447

The list of prime factors of all numbers are

Prime factors of 973 are 7 x 139

Prime factors of 372 are 2 x 2 x 3 x 31

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

Prime factors of 447 are 3 x 149

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

Given numbers are 973, 372, 644, 447

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

Apply this formula for all numbers.

Step1:

LCM(973, 372) = 361956

GCD(973, 372) = ( 973 x 372 ) / 361956

= 973 / 372

= 973

Step2:

LCM(1, 644) = 644

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

= 1 / 644

= 1

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 973, 372, 644, 447 is 1
