Given numbers are 214, 154, 447, 646

The list of prime factors of all numbers are

Prime factors of 214 are 2 x 107

Prime factors of 154 are 2 x 7 x 11

Prime factors of 447 are 3 x 149

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 214, 154, 447, 646

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

Apply this formula for all numbers.

Step1:

LCM(214, 154) = 16478

GCD(214, 154) = ( 214 x 154 ) / 16478

= 214 / 154

= 214

Step2:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 214, 154, 447, 646 is 1
