Given numbers are 785, 228, 480, 421

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 421 are 421

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

Given numbers are 785, 228, 480, 421

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

Apply this formula for all numbers.

Step1:

LCM(785, 228) = 178980

GCD(785, 228) = ( 785 x 228 ) / 178980

= 785 / 228

= 785

Step2:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 785, 228, 480, 421 is 1
