Given numbers are 385, 630, 855, 558

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 558 are 2 x 3 x 3 x 31

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

Given numbers are 385, 630, 855, 558

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

Apply this formula for all numbers.

Step1:

LCM(385, 630) = 6930

GCD(385, 630) = ( 385 x 630 ) / 6930

= 385 / 630

= 385

Step2:

LCM(35, 855) = 5985

GCD(35, 855) = ( 35 x 855 ) / 5985

= 35 / 855

= 35

Step3:

LCM(5, 558) = 2790

GCD(5, 558) = ( 5 x 558 ) / 2790

= 5 / 558

= 5

So, Greatest Common Divisor of 385, 630, 855, 558 is 1
