Given numbers are 209, 928, 100, 438

The list of prime factors of all numbers are

Prime factors of 209 are 11 x 19

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 438 are 2 x 3 x 73

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

Given numbers are 209, 928, 100, 438

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

Apply this formula for all numbers.

Step1:

LCM(209, 928) = 193952

GCD(209, 928) = ( 209 x 928 ) / 193952

= 209 / 928

= 209

Step2:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 209, 928, 100, 438 is 1
