Given numbers are 512, 380, 871, 645

The list of prime factors of all numbers are

Prime factors of 512 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 871 are 13 x 67

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 512, 380, 871, 645

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

Apply this formula for all numbers.

Step1:

LCM(512, 380) = 48640

GCD(512, 380) = ( 512 x 380 ) / 48640

= 512 / 380

= 512

Step2:

LCM(4, 871) = 3484

GCD(4, 871) = ( 4 x 871 ) / 3484

= 4 / 871

= 4

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 512, 380, 871, 645 is 1
