Given numbers are 430, 856, 209, 218

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 209 are 11 x 19

Prime factors of 218 are 2 x 109

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

Given numbers are 430, 856, 209, 218

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

Apply this formula for all numbers.

Step1:

LCM(430, 856) = 184040

GCD(430, 856) = ( 430 x 856 ) / 184040

= 430 / 856

= 430

Step2:

LCM(2, 209) = 418

GCD(2, 209) = ( 2 x 209 ) / 418

= 2 / 209

= 2

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 430, 856, 209, 218 is 1
