Given numbers are 665, 651, 239, 768

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 651 are 3 x 7 x 31

Prime factors of 239 are 239

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

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

Given numbers are 665, 651, 239, 768

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

Apply this formula for all numbers.

Step1:

LCM(665, 651) = 61845

GCD(665, 651) = ( 665 x 651 ) / 61845

= 665 / 651

= 665

Step2:

LCM(7, 239) = 1673

GCD(7, 239) = ( 7 x 239 ) / 1673

= 7 / 239

= 7

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 665, 651, 239, 768 is 1
