Given numbers are 398, 871, 784, 672

The list of prime factors of all numbers are

Prime factors of 398 are 2 x 199

Prime factors of 871 are 13 x 67

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

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

Given numbers are 398, 871, 784, 672

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

Apply this formula for all numbers.

Step1:

LCM(398, 871) = 346658

GCD(398, 871) = ( 398 x 871 ) / 346658

= 398 / 871

= 398

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 398, 871, 784, 672 is 1
