Given numbers are 105, 303, 248, 639

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 303 are 3 x 101

Prime factors of 248 are 2 x 2 x 2 x 31

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 105, 303, 248, 639

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

Apply this formula for all numbers.

Step1:

LCM(105, 303) = 10605

GCD(105, 303) = ( 105 x 303 ) / 10605

= 105 / 303

= 105

Step2:

LCM(3, 248) = 744

GCD(3, 248) = ( 3 x 248 ) / 744

= 3 / 248

= 3

Step3:

LCM(1, 639) = 639

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

= 1 / 639

= 1

So, Greatest Common Divisor of 105, 303, 248, 639 is 1
