Given numbers are 387, 270, 931, 805

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 931 are 7 x 7 x 19

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 387, 270, 931, 805

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

Apply this formula for all numbers.

Step1:

LCM(387, 270) = 11610

GCD(387, 270) = ( 387 x 270 ) / 11610

= 387 / 270

= 387

Step2:

LCM(9, 931) = 8379

GCD(9, 931) = ( 9 x 931 ) / 8379

= 9 / 931

= 9

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 387, 270, 931, 805 is 1
