Given numbers are 621, 163, 810, 193

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 163 are 163

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 193 are 193

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

Given numbers are 621, 163, 810, 193

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

Apply this formula for all numbers.

Step1:

LCM(621, 163) = 101223

GCD(621, 163) = ( 621 x 163 ) / 101223

= 621 / 163

= 621

Step2:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

Step3:

LCM(1, 193) = 193

GCD(1, 193) = ( 1 x 193 ) / 193

= 1 / 193

= 1

So, Greatest Common Divisor of 621, 163, 810, 193 is 1
