Given numbers are 801, 505, 564, 423

The list of prime factors of all numbers are

Prime factors of 801 are 3 x 3 x 89

Prime factors of 505 are 5 x 101

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 423 are 3 x 3 x 47

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

Given numbers are 801, 505, 564, 423

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

Apply this formula for all numbers.

Step1:

LCM(801, 505) = 404505

GCD(801, 505) = ( 801 x 505 ) / 404505

= 801 / 505

= 801

Step2:

LCM(1, 564) = 564

GCD(1, 564) = ( 1 x 564 ) / 564

= 1 / 564

= 1

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 801, 505, 564, 423 is 1
