Given numbers are 801, 505, 222, 644

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 222 are 2 x 3 x 37

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 801, 505, 222, 644

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, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 801, 505, 222, 644 is 1
