Given numbers are 641, 644, 200, 385

The list of prime factors of all numbers are

Prime factors of 641 are 641

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

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 385 are 5 x 7 x 11

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

Given numbers are 641, 644, 200, 385

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

Apply this formula for all numbers.

Step1:

LCM(641, 644) = 412804

GCD(641, 644) = ( 641 x 644 ) / 412804

= 641 / 644

= 641

Step2:

LCM(1, 200) = 200

GCD(1, 200) = ( 1 x 200 ) / 200

= 1 / 200

= 1

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 641, 644, 200, 385 is 1
