The list of prime factors of all numbers are

Prime factors of 543 are 3 x 181

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Given numbers are 543, 945, 208, 784

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

Apply this formula for all numbers.

Step1:

LCM(543, 945) = 171045

GCD(543, 945) = ( 543 x 945 ) / 171045

= 543 / 945

= 543

Step2:

LCM(3, 208) = 624

GCD(3, 208) = ( 3 x 208 ) / 624

= 3 / 208

= 3

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 543, 945, 208, 784 is 1
