Given numbers are 445, 771, 672, 687

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 771 are 3 x 257

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

Prime factors of 687 are 3 x 229

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

Given numbers are 445, 771, 672, 687

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

Apply this formula for all numbers.

Step1:

LCM(445, 771) = 343095

GCD(445, 771) = ( 445 x 771 ) / 343095

= 445 / 771

= 445

Step2:

LCM(1, 672) = 672

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

= 1 / 672

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 445, 771, 672, 687 is 1
