Given numbers are 403, 660, 515, 807

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 515 are 5 x 103

Prime factors of 807 are 3 x 269

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

Given numbers are 403, 660, 515, 807

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

Apply this formula for all numbers.

Step1:

LCM(403, 660) = 265980

GCD(403, 660) = ( 403 x 660 ) / 265980

= 403 / 660

= 403

Step2:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

Step3:

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

= 1 / 807

= 1

So, Greatest Common Divisor of 403, 660, 515, 807 is 1
