Given numbers are 918, 915, 579, 391

The list of prime factors of all numbers are

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

Prime factors of 915 are 3 x 5 x 61

Prime factors of 579 are 3 x 193

Prime factors of 391 are 17 x 23

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

Given numbers are 918, 915, 579, 391

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

Apply this formula for all numbers.

Step1:

LCM(918, 915) = 279990

GCD(918, 915) = ( 918 x 915 ) / 279990

= 918 / 915

= 918

Step2:

LCM(3, 579) = 579

GCD(3, 579) = ( 3 x 579 ) / 579

= 3 / 579

= 3

Step3:

LCM(3, 391) = 1173

GCD(3, 391) = ( 3 x 391 ) / 1173

= 3 / 391

= 3

So, Greatest Common Divisor of 918, 915, 579, 391 is 1
