Given numbers are 805, 672, 768, 453

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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 453 are 3 x 151

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

Given numbers are 805, 672, 768, 453

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

Apply this formula for all numbers.

Step1:

LCM(805, 672) = 77280

GCD(805, 672) = ( 805 x 672 ) / 77280

= 805 / 672

= 805

Step2:

LCM(7, 768) = 5376

GCD(7, 768) = ( 7 x 768 ) / 5376

= 7 / 768

= 7

Step3:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

So, Greatest Common Divisor of 805, 672, 768, 453 is 1
