Given numbers are 448, 394, 765, 257

The list of prime factors of all numbers are

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

Prime factors of 394 are 2 x 197

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 257 are 257

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

Given numbers are 448, 394, 765, 257

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

Apply this formula for all numbers.

Step1:

LCM(448, 394) = 88256

GCD(448, 394) = ( 448 x 394 ) / 88256

= 448 / 394

= 448

Step2:

LCM(2, 765) = 1530

GCD(2, 765) = ( 2 x 765 ) / 1530

= 2 / 765

= 2

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 448, 394, 765, 257 is 1
