Given numbers are 397, 465, 515, 672

The list of prime factors of all numbers are

Prime factors of 397 are 397

Prime factors of 465 are 3 x 5 x 31

Prime factors of 515 are 5 x 103

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 397, 465, 515, 672

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

Apply this formula for all numbers.

Step1:

LCM(397, 465) = 184605

GCD(397, 465) = ( 397 x 465 ) / 184605

= 397 / 465

= 397

Step2:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 397, 465, 515, 672 is 1
