Given numbers are 399, 448, 606, 407

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 606 are 2 x 3 x 101

Prime factors of 407 are 11 x 37

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

Given numbers are 399, 448, 606, 407

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

Apply this formula for all numbers.

Step1:

LCM(399, 448) = 25536

GCD(399, 448) = ( 399 x 448 ) / 25536

= 399 / 448

= 399

Step2:

LCM(7, 606) = 4242

GCD(7, 606) = ( 7 x 606 ) / 4242

= 7 / 606

= 7

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 399, 448, 606, 407 is 1
