Given numbers are 390, 826, 556, 543

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 826 are 2 x 7 x 59

Prime factors of 556 are 2 x 2 x 139

Prime factors of 543 are 3 x 181

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

Given numbers are 390, 826, 556, 543

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

Apply this formula for all numbers.

Step1:

LCM(390, 826) = 161070

GCD(390, 826) = ( 390 x 826 ) / 161070

= 390 / 826

= 390

Step2:

LCM(2, 556) = 556

GCD(2, 556) = ( 2 x 556 ) / 556

= 2 / 556

= 2

Step3:

LCM(2, 543) = 1086

GCD(2, 543) = ( 2 x 543 ) / 1086

= 2 / 543

= 2

So, Greatest Common Divisor of 390, 826, 556, 543 is 1
