Given numbers are 330, 543, 388, 781

The list of prime factors of all numbers are

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 543 are 3 x 181

Prime factors of 388 are 2 x 2 x 97

Prime factors of 781 are 11 x 71

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

Given numbers are 330, 543, 388, 781

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

Apply this formula for all numbers.

Step1:

LCM(330, 543) = 59730

GCD(330, 543) = ( 330 x 543 ) / 59730

= 330 / 543

= 330

Step2:

LCM(3, 388) = 1164

GCD(3, 388) = ( 3 x 388 ) / 1164

= 3 / 388

= 3

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 330, 543, 388, 781 is 1
