Given numbers are 678, 928, 408, 213

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 213 are 3 x 71

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

Given numbers are 678, 928, 408, 213

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

Apply this formula for all numbers.

Step1:

LCM(678, 928) = 314592

GCD(678, 928) = ( 678 x 928 ) / 314592

= 678 / 928

= 678

Step2:

LCM(2, 408) = 408

GCD(2, 408) = ( 2 x 408 ) / 408

= 2 / 408

= 2

Step3:

LCM(2, 213) = 426

GCD(2, 213) = ( 2 x 213 ) / 426

= 2 / 213

= 2

So, Greatest Common Divisor of 678, 928, 408, 213 is 1
