Given numbers are 387, 371, 103, 644

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 371 are 7 x 53

Prime factors of 103 are 103

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 387, 371, 103, 644

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

Apply this formula for all numbers.

Step1:

LCM(387, 371) = 143577

GCD(387, 371) = ( 387 x 371 ) / 143577

= 387 / 371

= 387

Step2:

LCM(1, 103) = 103

GCD(1, 103) = ( 1 x 103 ) / 103

= 1 / 103

= 1

Step3:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 387, 371, 103, 644 is 1
