Given numbers are 644, 738, 452, 855

The list of prime factors of all numbers are

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

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 452 are 2 x 2 x 113

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 644, 738, 452, 855

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

Apply this formula for all numbers.

Step1:

LCM(644, 738) = 237636

GCD(644, 738) = ( 644 x 738 ) / 237636

= 644 / 738

= 644

Step2:

LCM(2, 452) = 452

GCD(2, 452) = ( 2 x 452 ) / 452

= 2 / 452

= 2

Step3:

LCM(2, 855) = 1710

GCD(2, 855) = ( 2 x 855 ) / 1710

= 2 / 855

= 2

So, Greatest Common Divisor of 644, 738, 452, 855 is 1
