Given numbers are 643, 258, 384, 126

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 258 are 2 x 3 x 43

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 126 are 2 x 3 x 3 x 7

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

Given numbers are 643, 258, 384, 126

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

Apply this formula for all numbers.

Step1:

LCM(643, 258) = 165894

GCD(643, 258) = ( 643 x 258 ) / 165894

= 643 / 258

= 643

Step2:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 643, 258, 384, 126 is 1
