Given numbers are 205, 480, 917, 684

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 917 are 7 x 131

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 205, 480, 917, 684

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

Apply this formula for all numbers.

Step1:

LCM(205, 480) = 19680

GCD(205, 480) = ( 205 x 480 ) / 19680

= 205 / 480

= 205

Step2:

LCM(5, 917) = 4585

GCD(5, 917) = ( 5 x 917 ) / 4585

= 5 / 917

= 5

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 205, 480, 917, 684 is 1
