Given numbers are 390, 986, 916, 521

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 986 are 2 x 17 x 29

Prime factors of 916 are 2 x 2 x 229

Prime factors of 521 are 521

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

Given numbers are 390, 986, 916, 521

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

Apply this formula for all numbers.

Step1:

LCM(390, 986) = 192270

GCD(390, 986) = ( 390 x 986 ) / 192270

= 390 / 986

= 390

Step2:

LCM(2, 916) = 916

GCD(2, 916) = ( 2 x 916 ) / 916

= 2 / 916

= 2

Step3:

LCM(2, 521) = 1042

GCD(2, 521) = ( 2 x 521 ) / 1042

= 2 / 521

= 2

So, Greatest Common Divisor of 390, 986, 916, 521 is 1
