Given numbers are 783, 507, 855, 320

The list of prime factors of all numbers are

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 507 are 3 x 13 x 13

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

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 783, 507, 855, 320

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

Apply this formula for all numbers.

Step1:

LCM(783, 507) = 132327

GCD(783, 507) = ( 783 x 507 ) / 132327

= 783 / 507

= 783

Step2:

LCM(3, 855) = 855

GCD(3, 855) = ( 3 x 855 ) / 855

= 3 / 855

= 3

Step3:

LCM(3, 320) = 960

GCD(3, 320) = ( 3 x 320 ) / 960

= 3 / 320

= 3

So, Greatest Common Divisor of 783, 507, 855, 320 is 1
