Given numbers are 387, 456, 455, 302

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 455 are 5 x 7 x 13

Prime factors of 302 are 2 x 151

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

Given numbers are 387, 456, 455, 302

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

Apply this formula for all numbers.

Step1:

LCM(387, 456) = 58824

GCD(387, 456) = ( 387 x 456 ) / 58824

= 387 / 456

= 387

Step2:

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

Step3:

LCM(1, 302) = 302

GCD(1, 302) = ( 1 x 302 ) / 302

= 1 / 302

= 1

So, Greatest Common Divisor of 387, 456, 455, 302 is 1
