Given numbers are 644, 845, 505, 876

The list of prime factors of all numbers are

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

Prime factors of 845 are 5 x 13 x 13

Prime factors of 505 are 5 x 101

Prime factors of 876 are 2 x 2 x 3 x 73

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

Given numbers are 644, 845, 505, 876

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

Apply this formula for all numbers.

Step1:

LCM(644, 845) = 544180

GCD(644, 845) = ( 644 x 845 ) / 544180

= 644 / 845

= 644

Step2:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

Step3:

LCM(1, 876) = 876

GCD(1, 876) = ( 1 x 876 ) / 876

= 1 / 876

= 1

So, Greatest Common Divisor of 644, 845, 505, 876 is 1
