Given numbers are 445, 671, 672, 619

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 671 are 11 x 61

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 619 are 619

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

Given numbers are 445, 671, 672, 619

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

Apply this formula for all numbers.

Step1:

LCM(445, 671) = 298595

GCD(445, 671) = ( 445 x 671 ) / 298595

= 445 / 671

= 445

Step2:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

Step3:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

So, Greatest Common Divisor of 445, 671, 672, 619 is 1
