Given numbers are 180, 684, 918, 485

The list of prime factors of all numbers are

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

Prime factors of 485 are 5 x 97

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

Given numbers are 180, 684, 918, 485

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

Apply this formula for all numbers.

Step1:

LCM(180, 684) = 3420

GCD(180, 684) = ( 180 x 684 ) / 3420

= 180 / 684

= 180

Step2:

LCM(36, 918) = 1836

GCD(36, 918) = ( 36 x 918 ) / 1836

= 36 / 918

= 36

Step3:

LCM(18, 485) = 8730

GCD(18, 485) = ( 18 x 485 ) / 8730

= 18 / 485

= 18

So, Greatest Common Divisor of 180, 684, 918, 485 is 1
