Given numbers are 768, 640, 515, 658

The list of prime factors of all numbers are

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 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 515 are 5 x 103

Prime factors of 658 are 2 x 7 x 47

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

Given numbers are 768, 640, 515, 658

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

Apply this formula for all numbers.

Step1:

LCM(768, 640) = 3840

GCD(768, 640) = ( 768 x 640 ) / 3840

= 768 / 640

= 768

Step2:

LCM(128, 515) = 65920

GCD(128, 515) = ( 128 x 515 ) / 65920

= 128 / 515

= 128

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 768, 640, 515, 658 is 1
