Given numbers are 378, 194, 720, 511

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 194 are 2 x 97

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 511 are 7 x 73

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

Given numbers are 378, 194, 720, 511

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

Apply this formula for all numbers.

Step1:

LCM(378, 194) = 36666

GCD(378, 194) = ( 378 x 194 ) / 36666

= 378 / 194

= 378

Step2:

LCM(2, 720) = 720

GCD(2, 720) = ( 2 x 720 ) / 720

= 2 / 720

= 2

Step3:

LCM(2, 511) = 1022

GCD(2, 511) = ( 2 x 511 ) / 1022

= 2 / 511

= 2

So, Greatest Common Divisor of 378, 194, 720, 511 is 1
