Given numbers are 644, 120, 567, 275

The list of prime factors of all numbers are

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

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 567 are 3 x 3 x 3 x 3 x 7

Prime factors of 275 are 5 x 5 x 11

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

Given numbers are 644, 120, 567, 275

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

Apply this formula for all numbers.

Step1:

LCM(644, 120) = 19320

GCD(644, 120) = ( 644 x 120 ) / 19320

= 644 / 120

= 644

Step2:

LCM(4, 567) = 2268

GCD(4, 567) = ( 4 x 567 ) / 2268

= 4 / 567

= 4

Step3:

LCM(1, 275) = 275

GCD(1, 275) = ( 1 x 275 ) / 275

= 1 / 275

= 1

So, Greatest Common Divisor of 644, 120, 567, 275 is 1
