Given numbers are 522, 147, 391, 257

The list of prime factors of all numbers are

Prime factors of 522 are 2 x 3 x 3 x 29

Prime factors of 147 are 3 x 7 x 7

Prime factors of 391 are 17 x 23

Prime factors of 257 are 257

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

Given numbers are 522, 147, 391, 257

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

Apply this formula for all numbers.

Step1:

LCM(522, 147) = 25578

GCD(522, 147) = ( 522 x 147 ) / 25578

= 522 / 147

= 522

Step2:

LCM(3, 391) = 1173

GCD(3, 391) = ( 3 x 391 ) / 1173

= 3 / 391

= 3

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 522, 147, 391, 257 is 1
