Given numbers are 513, 192, 991, 420

The list of prime factors of all numbers are

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 991 are 991

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 513, 192, 991, 420

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

Apply this formula for all numbers.

Step1:

LCM(513, 192) = 32832

GCD(513, 192) = ( 513 x 192 ) / 32832

= 513 / 192

= 513

Step2:

LCM(3, 991) = 2973

GCD(3, 991) = ( 3 x 991 ) / 2973

= 3 / 991

= 3

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 513, 192, 991, 420 is 1
