Given numbers are 868, 358, 415, 438

The list of prime factors of all numbers are

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 358 are 2 x 179

Prime factors of 415 are 5 x 83

Prime factors of 438 are 2 x 3 x 73

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

Given numbers are 868, 358, 415, 438

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

Apply this formula for all numbers.

Step1:

LCM(868, 358) = 155372

GCD(868, 358) = ( 868 x 358 ) / 155372

= 868 / 358

= 868

Step2:

LCM(2, 415) = 830

GCD(2, 415) = ( 2 x 415 ) / 830

= 2 / 415

= 2

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 868, 358, 415, 438 is 1
