Given numbers are 189, 912, 403, 253

The list of prime factors of all numbers are

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 403 are 13 x 31

Prime factors of 253 are 11 x 23

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

Given numbers are 189, 912, 403, 253

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

Apply this formula for all numbers.

Step1:

LCM(189, 912) = 57456

GCD(189, 912) = ( 189 x 912 ) / 57456

= 189 / 912

= 189

Step2:

LCM(3, 403) = 1209

GCD(3, 403) = ( 3 x 403 ) / 1209

= 3 / 403

= 3

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 189, 912, 403, 253 is 1
