Given numbers are 680, 155, 403, 914

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 155 are 5 x 31

Prime factors of 403 are 13 x 31

Prime factors of 914 are 2 x 457

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

Given numbers are 680, 155, 403, 914

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

Apply this formula for all numbers.

Step1:

LCM(680, 155) = 21080

GCD(680, 155) = ( 680 x 155 ) / 21080

= 680 / 155

= 680

Step2:

LCM(5, 403) = 2015

GCD(5, 403) = ( 5 x 403 ) / 2015

= 5 / 403

= 5

Step3:

LCM(1, 914) = 914

GCD(1, 914) = ( 1 x 914 ) / 914

= 1 / 914

= 1

So, Greatest Common Divisor of 680, 155, 403, 914 is 1
