Given numbers are 438, 598, 135, 858

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 598 are 2 x 13 x 23

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 858 are 2 x 3 x 11 x 13

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

Given numbers are 438, 598, 135, 858

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

Apply this formula for all numbers.

Step1:

LCM(438, 598) = 130962

GCD(438, 598) = ( 438 x 598 ) / 130962

= 438 / 598

= 438

Step2:

LCM(2, 135) = 270

GCD(2, 135) = ( 2 x 135 ) / 270

= 2 / 135

= 2

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 438, 598, 135, 858 is 1
