Given numbers are 520, 826, 423, 639

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 826 are 2 x 7 x 59

Prime factors of 423 are 3 x 3 x 47

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 520, 826, 423, 639

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

Apply this formula for all numbers.

Step1:

LCM(520, 826) = 214760

GCD(520, 826) = ( 520 x 826 ) / 214760

= 520 / 826

= 520

Step2:

LCM(2, 423) = 846

GCD(2, 423) = ( 2 x 423 ) / 846

= 2 / 423

= 2

Step3:

LCM(1, 639) = 639

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

= 1 / 639

= 1

So, Greatest Common Divisor of 520, 826, 423, 639 is 1
