Given numbers are 435, 286, 687, 438

The list of prime factors of all numbers are

Prime factors of 435 are 3 x 5 x 29

Prime factors of 286 are 2 x 11 x 13

Prime factors of 687 are 3 x 229

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 435, 286, 687, 438

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

Apply this formula for all numbers.

Step1:

LCM(435, 286) = 124410

GCD(435, 286) = ( 435 x 286 ) / 124410

= 435 / 286

= 435

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 438) = 438

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

= 1 / 438

= 1

So, Greatest Common Divisor of 435, 286, 687, 438 is 1
