Given numbers are 788, 320, 691, 636

The list of prime factors of all numbers are

Prime factors of 788 are 2 x 2 x 197

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

Prime factors of 691 are 691

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 788, 320, 691, 636

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

Apply this formula for all numbers.

Step1:

LCM(788, 320) = 63040

GCD(788, 320) = ( 788 x 320 ) / 63040

= 788 / 320

= 788

Step2:

LCM(4, 691) = 2764

GCD(4, 691) = ( 4 x 691 ) / 2764

= 4 / 691

= 4

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 788, 320, 691, 636 is 1
