Given numbers are 320, 855, 247, 787

The list of prime factors of all numbers are

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

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 247 are 13 x 19

Prime factors of 787 are 787

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

Given numbers are 320, 855, 247, 787

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

Apply this formula for all numbers.

Step1:

LCM(320, 855) = 54720

GCD(320, 855) = ( 320 x 855 ) / 54720

= 320 / 855

= 320

Step2:

LCM(5, 247) = 1235

GCD(5, 247) = ( 5 x 247 ) / 1235

= 5 / 247

= 5

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 320, 855, 247, 787 is 1
