Given numbers are 406, 191, 672, 670

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 191 are 191

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

Prime factors of 670 are 2 x 5 x 67

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

Given numbers are 406, 191, 672, 670

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

Apply this formula for all numbers.

Step1:

LCM(406, 191) = 77546

GCD(406, 191) = ( 406 x 191 ) / 77546

= 406 / 191

= 406

Step2:

LCM(1, 672) = 672

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

= 1 / 672

= 1

Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 406, 191, 672, 670 is 1
