Given numbers are 838, 641, 170, 243

The list of prime factors of all numbers are

Prime factors of 838 are 2 x 419

Prime factors of 641 are 641

Prime factors of 170 are 2 x 5 x 17

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 838, 641, 170, 243

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

Apply this formula for all numbers.

Step1:

LCM(838, 641) = 537158

GCD(838, 641) = ( 838 x 641 ) / 537158

= 838 / 641

= 838

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 838, 641, 170, 243 is 1
