Given numbers are 810, 124, 305, 425

The list of prime factors of all numbers are

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

Prime factors of 124 are 2 x 2 x 31

Prime factors of 305 are 5 x 61

Prime factors of 425 are 5 x 5 x 17

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

Given numbers are 810, 124, 305, 425

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

Apply this formula for all numbers.

Step1:

LCM(810, 124) = 50220

GCD(810, 124) = ( 810 x 124 ) / 50220

= 810 / 124

= 810

Step2:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 810, 124, 305, 425 is 1
