Given numbers are 843, 641, 208, 390

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 641 are 641

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 843, 641, 208, 390

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

Apply this formula for all numbers.

Step1:

LCM(843, 641) = 540363

GCD(843, 641) = ( 843 x 641 ) / 540363

= 843 / 641

= 843

Step2:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 843, 641, 208, 390 is 1
