Given numbers are 861, 906, 214, 672

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 906 are 2 x 3 x 151

Prime factors of 214 are 2 x 107

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 861, 906, 214, 672

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

Apply this formula for all numbers.

Step1:

LCM(861, 906) = 260022

GCD(861, 906) = ( 861 x 906 ) / 260022

= 861 / 906

= 861

Step2:

LCM(3, 214) = 642

GCD(3, 214) = ( 3 x 214 ) / 642

= 3 / 214

= 3

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 861, 906, 214, 672 is 1
