Given numbers are 395, 690, 447, 715

The list of prime factors of all numbers are

Prime factors of 395 are 5 x 79

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 447 are 3 x 149

Prime factors of 715 are 5 x 11 x 13

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

Given numbers are 395, 690, 447, 715

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

Apply this formula for all numbers.

Step1:

LCM(395, 690) = 54510

GCD(395, 690) = ( 395 x 690 ) / 54510

= 395 / 690

= 395

Step2:

LCM(5, 447) = 2235

GCD(5, 447) = ( 5 x 447 ) / 2235

= 5 / 447

= 5

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 395, 690, 447, 715 is 1
