Given numbers are 768, 456, 130, 641

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 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 130 are 2 x 5 x 13

Prime factors of 641 are 641

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

Given numbers are 768, 456, 130, 641

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

Apply this formula for all numbers.

Step1:

LCM(768, 456) = 14592

GCD(768, 456) = ( 768 x 456 ) / 14592

= 768 / 456

= 768

Step2:

LCM(24, 130) = 1560

GCD(24, 130) = ( 24 x 130 ) / 1560

= 24 / 130

= 24

Step3:

LCM(2, 641) = 1282

GCD(2, 641) = ( 2 x 641 ) / 1282

= 2 / 641

= 2

So, Greatest Common Divisor of 768, 456, 130, 641 is 1
