Given numbers are 667, 656, 765, 442

The list of prime factors of all numbers are

Prime factors of 667 are 23 x 29

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 667, 656, 765, 442

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

Apply this formula for all numbers.

Step1:

LCM(667, 656) = 437552

GCD(667, 656) = ( 667 x 656 ) / 437552

= 667 / 656

= 667

Step2:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

Step3:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

So, Greatest Common Divisor of 667, 656, 765, 442 is 1
