Given numbers are 646, 547, 639, 480

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 547 are 547

Prime factors of 639 are 3 x 3 x 71

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 646, 547, 639, 480

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

Apply this formula for all numbers.

Step1:

LCM(646, 547) = 353362

GCD(646, 547) = ( 646 x 547 ) / 353362

= 646 / 547

= 646

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 646, 547, 639, 480 is 1
