Given numbers are 455, 904, 665, 240

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 904 are 2 x 2 x 2 x 113

Prime factors of 665 are 5 x 7 x 19

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 455, 904, 665, 240

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

Apply this formula for all numbers.

Step1:

LCM(455, 904) = 411320

GCD(455, 904) = ( 455 x 904 ) / 411320

= 455 / 904

= 455

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 455, 904, 665, 240 is 1
