Given numbers are 680, 708, 409, 699

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 708 are 2 x 2 x 3 x 59

Prime factors of 409 are 409

Prime factors of 699 are 3 x 233

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

Given numbers are 680, 708, 409, 699

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

Apply this formula for all numbers.

Step1:

LCM(680, 708) = 120360

GCD(680, 708) = ( 680 x 708 ) / 120360

= 680 / 708

= 680

Step2:

LCM(4, 409) = 1636

GCD(4, 409) = ( 4 x 409 ) / 1636

= 4 / 409

= 4

Step3:

LCM(1, 699) = 699

GCD(1, 699) = ( 1 x 699 ) / 699

= 1 / 699

= 1

So, Greatest Common Divisor of 680, 708, 409, 699 is 1
