Given numbers are 478, 789, 828, 666

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 789 are 3 x 263

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 666 are 2 x 3 x 3 x 37

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

Given numbers are 478, 789, 828, 666

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

Apply this formula for all numbers.

Step1:

LCM(478, 789) = 377142

GCD(478, 789) = ( 478 x 789 ) / 377142

= 478 / 789

= 478

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 478, 789, 828, 666 is 1
