Given numbers are 445, 556, 492, 805

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 556 are 2 x 2 x 139

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 445, 556, 492, 805

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

Apply this formula for all numbers.

Step1:

LCM(445, 556) = 247420

GCD(445, 556) = ( 445 x 556 ) / 247420

= 445 / 556

= 445

Step2:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 445, 556, 492, 805 is 1
