Given numbers are 878, 689, 923, 480

The list of prime factors of all numbers are

Prime factors of 878 are 2 x 439

Prime factors of 689 are 13 x 53

Prime factors of 923 are 13 x 71

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 878, 689, 923, 480

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

Apply this formula for all numbers.

Step1:

LCM(878, 689) = 604942

GCD(878, 689) = ( 878 x 689 ) / 604942

= 878 / 689

= 878

Step2:

LCM(1, 923) = 923

GCD(1, 923) = ( 1 x 923 ) / 923

= 1 / 923

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 878, 689, 923, 480 is 1
