Given numbers are 646, 211, 474, 413

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 211 are 211

Prime factors of 474 are 2 x 3 x 79

Prime factors of 413 are 7 x 59

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

Given numbers are 646, 211, 474, 413

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

Apply this formula for all numbers.

Step1:

LCM(646, 211) = 136306

GCD(646, 211) = ( 646 x 211 ) / 136306

= 646 / 211

= 646

Step2:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

Step3:

LCM(1, 413) = 413

GCD(1, 413) = ( 1 x 413 ) / 413

= 1 / 413

= 1

So, Greatest Common Divisor of 646, 211, 474, 413 is 1
