Given numbers are 378, 216, 521, 191

The list of prime factors of all numbers are

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 521 are 521

Prime factors of 191 are 191

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

Given numbers are 378, 216, 521, 191

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

Apply this formula for all numbers.

Step1:

LCM(378, 216) = 1512

GCD(378, 216) = ( 378 x 216 ) / 1512

= 378 / 216

= 378

Step2:

LCM(54, 521) = 28134

GCD(54, 521) = ( 54 x 521 ) / 28134

= 54 / 521

= 54

Step3:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

So, Greatest Common Divisor of 378, 216, 521, 191 is 1
