Given numbers are 646, 638, 659, 662

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 638 are 2 x 11 x 29

Prime factors of 659 are 659

Prime factors of 662 are 2 x 331

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

Given numbers are 646, 638, 659, 662

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

Apply this formula for all numbers.

Step1:

LCM(646, 638) = 206074

GCD(646, 638) = ( 646 x 638 ) / 206074

= 646 / 638

= 646

Step2:

LCM(2, 659) = 1318

GCD(2, 659) = ( 2 x 659 ) / 1318

= 2 / 659

= 2

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 646, 638, 659, 662 is 1
