Given numbers are 438, 257, 924, 889

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 257 are 257

Prime factors of 924 are 2 x 2 x 3 x 7 x 11

Prime factors of 889 are 7 x 127

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

Given numbers are 438, 257, 924, 889

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

Apply this formula for all numbers.

Step1:

LCM(438, 257) = 112566

GCD(438, 257) = ( 438 x 257 ) / 112566

= 438 / 257

= 438

Step2:

LCM(1, 924) = 924

GCD(1, 924) = ( 1 x 924 ) / 924

= 1 / 924

= 1

Step3:

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

= 1 / 889

= 1

So, Greatest Common Divisor of 438, 257, 924, 889 is 1
