Given numbers are 672, 681, 773, 644

The list of prime factors of all numbers are

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

Prime factors of 681 are 3 x 227

Prime factors of 773 are 773

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 672, 681, 773, 644

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

Apply this formula for all numbers.

Step1:

LCM(672, 681) = 152544

GCD(672, 681) = ( 672 x 681 ) / 152544

= 672 / 681

= 672

Step2:

LCM(3, 773) = 2319

GCD(3, 773) = ( 3 x 773 ) / 2319

= 3 / 773

= 3

Step3:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 672, 681, 773, 644 is 1
