Given numbers are 820, 764, 556, 447

The list of prime factors of all numbers are

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

Prime factors of 764 are 2 x 2 x 191

Prime factors of 556 are 2 x 2 x 139

Prime factors of 447 are 3 x 149

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

Given numbers are 820, 764, 556, 447

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

Apply this formula for all numbers.

Step1:

LCM(820, 764) = 156620

GCD(820, 764) = ( 820 x 764 ) / 156620

= 820 / 764

= 820

Step2:

LCM(4, 556) = 556

GCD(4, 556) = ( 4 x 556 ) / 556

= 4 / 556

= 4

Step3:

LCM(4, 447) = 1788

GCD(4, 447) = ( 4 x 447 ) / 1788

= 4 / 447

= 4

So, Greatest Common Divisor of 820, 764, 556, 447 is 1
