Given numbers are 679, 756, 173, 145

The list of prime factors of all numbers are

Prime factors of 679 are 7 x 97

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 173 are 173

Prime factors of 145 are 5 x 29

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

Given numbers are 679, 756, 173, 145

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

Apply this formula for all numbers.

Step1:

LCM(679, 756) = 73332

GCD(679, 756) = ( 679 x 756 ) / 73332

= 679 / 756

= 679

Step2:

LCM(7, 173) = 1211

GCD(7, 173) = ( 7 x 173 ) / 1211

= 7 / 173

= 7

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 679, 756, 173, 145 is 1
