Given numbers are 687, 520, 693, 435

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 435 are 3 x 5 x 29

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

Given numbers are 687, 520, 693, 435

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

Apply this formula for all numbers.

Step1:

LCM(687, 520) = 357240

GCD(687, 520) = ( 687 x 520 ) / 357240

= 687 / 520

= 687

Step2:

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

= 1 / 693

= 1

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 687, 520, 693, 435 is 1
