Given numbers are 447, 315, 784, 381

The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 381 are 3 x 127

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

Given numbers are 447, 315, 784, 381

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

Apply this formula for all numbers.

Step1:

LCM(447, 315) = 46935

GCD(447, 315) = ( 447 x 315 ) / 46935

= 447 / 315

= 447

Step2:

LCM(3, 784) = 2352

GCD(3, 784) = ( 3 x 784 ) / 2352

= 3 / 784

= 3

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 447, 315, 784, 381 is 1
