Given numbers are 820, 305, 445, 788

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 305 are 5 x 61

Prime factors of 445 are 5 x 89

Prime factors of 788 are 2 x 2 x 197

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

Given numbers are 820, 305, 445, 788

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

Apply this formula for all numbers.

Step1:

LCM(820, 305) = 50020

GCD(820, 305) = ( 820 x 305 ) / 50020

= 820 / 305

= 820

Step2:

LCM(5, 445) = 445

GCD(5, 445) = ( 5 x 445 ) / 445

= 5 / 445

= 5

Step3:

LCM(5, 788) = 3940

GCD(5, 788) = ( 5 x 788 ) / 3940

= 5 / 788

= 5

So, Greatest Common Divisor of 820, 305, 445, 788 is 1
