Given numbers are 820, 401, 394, 523

The list of prime factors of all numbers are

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

Prime factors of 401 are 401

Prime factors of 394 are 2 x 197

Prime factors of 523 are 523

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

Given numbers are 820, 401, 394, 523

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

Apply this formula for all numbers.

Step1:

LCM(820, 401) = 328820

GCD(820, 401) = ( 820 x 401 ) / 328820

= 820 / 401

= 820

Step2:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

Step3:

LCM(1, 523) = 523

GCD(1, 523) = ( 1 x 523 ) / 523

= 1 / 523

= 1

So, Greatest Common Divisor of 820, 401, 394, 523 is 1
