Given numbers are 378, 426, 511, 261

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 426 are 2 x 3 x 71

Prime factors of 511 are 7 x 73

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 378, 426, 511, 261

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

Apply this formula for all numbers.

Step1:

LCM(378, 426) = 26838

GCD(378, 426) = ( 378 x 426 ) / 26838

= 378 / 426

= 378

Step2:

LCM(6, 511) = 3066

GCD(6, 511) = ( 6 x 511 ) / 3066

= 6 / 511

= 6

Step3:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

So, Greatest Common Divisor of 378, 426, 511, 261 is 1
