The list of prime factors of all numbers are

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 987 are 3 x 7 x 47

Prime factors of 785 are 5 x 157

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

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

Given numbers are 396, 987, 785, 918

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

Apply this formula for all numbers.

Step1:

LCM(396, 987) = 130284

GCD(396, 987) = ( 396 x 987 ) / 130284

= 396 / 987

= 396

Step2:

LCM(3, 785) = 2355

GCD(3, 785) = ( 3 x 785 ) / 2355

= 3 / 785

= 3

Step3:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

So, Greatest Common Divisor of 396, 987, 785, 918 is 1
