Given numbers are 440, 532, 388, 687

The list of prime factors of all numbers are

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 532 are 2 x 2 x 7 x 19

Prime factors of 388 are 2 x 2 x 97

Prime factors of 687 are 3 x 229

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

Given numbers are 440, 532, 388, 687

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

Apply this formula for all numbers.

Step1:

LCM(440, 532) = 58520

GCD(440, 532) = ( 440 x 532 ) / 58520

= 440 / 532

= 440

Step2:

LCM(4, 388) = 388

GCD(4, 388) = ( 4 x 388 ) / 388

= 4 / 388

= 4

Step3:

LCM(4, 687) = 2748

GCD(4, 687) = ( 4 x 687 ) / 2748

= 4 / 687

= 4

So, Greatest Common Divisor of 440, 532, 388, 687 is 1
