Given numbers are 438, 855, 128, 462

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

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

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 462 are 2 x 3 x 7 x 11

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

Given numbers are 438, 855, 128, 462

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

Apply this formula for all numbers.

Step1:

LCM(438, 855) = 124830

GCD(438, 855) = ( 438 x 855 ) / 124830

= 438 / 855

= 438

Step2:

LCM(3, 128) = 384

GCD(3, 128) = ( 3 x 128 ) / 384

= 3 / 128

= 3

Step3:

LCM(1, 462) = 462

GCD(1, 462) = ( 1 x 462 ) / 462

= 1 / 462

= 1

So, Greatest Common Divisor of 438, 855, 128, 462 is 1
