Given numbers are 123, 921, 486, 832

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 921 are 3 x 307

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 832 are 2 x 2 x 2 x 2 x 2 x 2 x 13

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

Given numbers are 123, 921, 486, 832

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

Apply this formula for all numbers.

Step1:

LCM(123, 921) = 37761

GCD(123, 921) = ( 123 x 921 ) / 37761

= 123 / 921

= 123

Step2:

LCM(3, 486) = 486

GCD(3, 486) = ( 3 x 486 ) / 486

= 3 / 486

= 3

Step3:

LCM(3, 832) = 2496

GCD(3, 832) = ( 3 x 832 ) / 2496

= 3 / 832

= 3

So, Greatest Common Divisor of 123, 921, 486, 832 is 1
