Given numbers are 487, 280, 440, 685

The list of prime factors of all numbers are

Prime factors of 487 are 487

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Prime factors of 685 are 5 x 137

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

Given numbers are 487, 280, 440, 685

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

Apply this formula for all numbers.

Step1:

LCM(487, 280) = 136360

GCD(487, 280) = ( 487 x 280 ) / 136360

= 487 / 280

= 487

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 487, 280, 440, 685 is 1
