Given numbers are 646, 920, 362, 321

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 362 are 2 x 181

Prime factors of 321 are 3 x 107

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

Given numbers are 646, 920, 362, 321

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

Apply this formula for all numbers.

Step1:

LCM(646, 920) = 297160

GCD(646, 920) = ( 646 x 920 ) / 297160

= 646 / 920

= 646

Step2:

LCM(2, 362) = 362

GCD(2, 362) = ( 2 x 362 ) / 362

= 2 / 362

= 2

Step3:

LCM(2, 321) = 642

GCD(2, 321) = ( 2 x 321 ) / 642

= 2 / 321

= 2

So, Greatest Common Divisor of 646, 920, 362, 321 is 1
