Given numbers are 799, 645, 800, 320

The list of prime factors of all numbers are

Prime factors of 799 are 17 x 47

Prime factors of 645 are 3 x 5 x 43

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 799, 645, 800, 320

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

Apply this formula for all numbers.

Step1:

LCM(799, 645) = 515355

GCD(799, 645) = ( 799 x 645 ) / 515355

= 799 / 645

= 799

Step2:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 799, 645, 800, 320 is 1
