Given numbers are 847, 738, 220, 789

The list of prime factors of all numbers are

Prime factors of 847 are 7 x 11 x 11

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 789 are 3 x 263

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

Given numbers are 847, 738, 220, 789

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

Apply this formula for all numbers.

Step1:

LCM(847, 738) = 625086

GCD(847, 738) = ( 847 x 738 ) / 625086

= 847 / 738

= 847

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 847, 738, 220, 789 is 1
