Given numbers are 920, 430, 822, 209

The list of prime factors of all numbers are

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 430 are 2 x 5 x 43

Prime factors of 822 are 2 x 3 x 137

Prime factors of 209 are 11 x 19

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

Given numbers are 920, 430, 822, 209

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

Apply this formula for all numbers.

Step1:

LCM(920, 430) = 39560

GCD(920, 430) = ( 920 x 430 ) / 39560

= 920 / 430

= 920

Step2:

LCM(10, 822) = 4110

GCD(10, 822) = ( 10 x 822 ) / 4110

= 10 / 822

= 10

Step3:

LCM(2, 209) = 418

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

= 2 / 209

= 2

So, Greatest Common Divisor of 920, 430, 822, 209 is 1
