Given numbers are 668, 768, 205, 790

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

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 205 are 5 x 41

Prime factors of 790 are 2 x 5 x 79

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

Given numbers are 668, 768, 205, 790

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

Apply this formula for all numbers.

Step1:

LCM(668, 768) = 128256

GCD(668, 768) = ( 668 x 768 ) / 128256

= 668 / 768

= 668

Step2:

LCM(4, 205) = 820

GCD(4, 205) = ( 4 x 205 ) / 820

= 4 / 205

= 4

Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

So, Greatest Common Divisor of 668, 768, 205, 790 is 1
