Given numbers are 765, 140, 768, 679

The list of prime factors of all numbers are

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 679 are 7 x 97

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

Given numbers are 765, 140, 768, 679

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

Apply this formula for all numbers.

Step1:

LCM(765, 140) = 21420

GCD(765, 140) = ( 765 x 140 ) / 21420

= 765 / 140

= 765

Step2:

LCM(5, 768) = 3840

GCD(5, 768) = ( 5 x 768 ) / 3840

= 5 / 768

= 5

Step3:

LCM(1, 679) = 679

GCD(1, 679) = ( 1 x 679 ) / 679

= 1 / 679

= 1

So, Greatest Common Divisor of 765, 140, 768, 679 is 1
