Given numbers are 209, 129, 400, 496

The list of prime factors of all numbers are

Prime factors of 209 are 11 x 19

Prime factors of 129 are 3 x 43

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 496 are 2 x 2 x 2 x 2 x 31

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

Given numbers are 209, 129, 400, 496

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

Apply this formula for all numbers.

Step1:

LCM(209, 129) = 26961

GCD(209, 129) = ( 209 x 129 ) / 26961

= 209 / 129

= 209

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 496) = 496

GCD(1, 496) = ( 1 x 496 ) / 496

= 1 / 496

= 1

So, Greatest Common Divisor of 209, 129, 400, 496 is 1
