Given numbers are 381, 865, 468, 720

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 865 are 5 x 173

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 381, 865, 468, 720

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

Apply this formula for all numbers.

Step1:

LCM(381, 865) = 329565

GCD(381, 865) = ( 381 x 865 ) / 329565

= 381 / 865

= 381

Step2:

LCM(1, 468) = 468

GCD(1, 468) = ( 1 x 468 ) / 468

= 1 / 468

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 381, 865, 468, 720 is 1
