Given numbers are 680, 885, 523, 685

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 885 are 3 x 5 x 59

Prime factors of 523 are 523

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 680, 885, 523, 685

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

Apply this formula for all numbers.

Step1:

LCM(680, 885) = 120360

GCD(680, 885) = ( 680 x 885 ) / 120360

= 680 / 885

= 680

Step2:

LCM(5, 523) = 2615

GCD(5, 523) = ( 5 x 523 ) / 2615

= 5 / 523

= 5

Step3:

LCM(1, 685) = 685

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

= 1 / 685

= 1

So, Greatest Common Divisor of 680, 885, 523, 685 is 1
