Given numbers are 930, 547, 845, 420

The list of prime factors of all numbers are

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 547 are 547

Prime factors of 845 are 5 x 13 x 13

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 930, 547, 845, 420

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

Apply this formula for all numbers.

Step1:

LCM(930, 547) = 508710

GCD(930, 547) = ( 930 x 547 ) / 508710

= 930 / 547

= 930

Step2:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 930, 547, 845, 420 is 1
