Given numbers are 672, 543, 878, 398

The list of prime factors of all numbers are

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 543 are 3 x 181

Prime factors of 878 are 2 x 439

Prime factors of 398 are 2 x 199

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

Given numbers are 672, 543, 878, 398

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

Apply this formula for all numbers.

Step1:

LCM(672, 543) = 121632

GCD(672, 543) = ( 672 x 543 ) / 121632

= 672 / 543

= 672

Step2:

LCM(3, 878) = 2634

GCD(3, 878) = ( 3 x 878 ) / 2634

= 3 / 878

= 3

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 672, 543, 878, 398 is 1
