Given numbers are 826, 398, 520, 407

The list of prime factors of all numbers are

Prime factors of 826 are 2 x 7 x 59

Prime factors of 398 are 2 x 199

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

Prime factors of 407 are 11 x 37

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

Given numbers are 826, 398, 520, 407

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

Apply this formula for all numbers.

Step1:

LCM(826, 398) = 164374

GCD(826, 398) = ( 826 x 398 ) / 164374

= 826 / 398

= 826

Step2:

LCM(2, 520) = 520

GCD(2, 520) = ( 2 x 520 ) / 520

= 2 / 520

= 2

Step3:

LCM(2, 407) = 814

GCD(2, 407) = ( 2 x 407 ) / 814

= 2 / 407

= 2

So, Greatest Common Divisor of 826, 398, 520, 407 is 1
