Given numbers are 646, 255, 784, 888

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 255 are 3 x 5 x 17

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 888 are 2 x 2 x 2 x 3 x 37

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

Given numbers are 646, 255, 784, 888

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

Apply this formula for all numbers.

Step1:

LCM(646, 255) = 9690

GCD(646, 255) = ( 646 x 255 ) / 9690

= 646 / 255

= 646

Step2:

LCM(17, 784) = 13328

GCD(17, 784) = ( 17 x 784 ) / 13328

= 17 / 784

= 17

Step3:

LCM(1, 888) = 888

GCD(1, 888) = ( 1 x 888 ) / 888

= 1 / 888

= 1

So, Greatest Common Divisor of 646, 255, 784, 888 is 1
