Given numbers are 455, 765, 382, 242

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

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

Prime factors of 382 are 2 x 191

Prime factors of 242 are 2 x 11 x 11

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

Given numbers are 455, 765, 382, 242

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

Apply this formula for all numbers.

Step1:

LCM(455, 765) = 69615

GCD(455, 765) = ( 455 x 765 ) / 69615

= 455 / 765

= 455

Step2:

LCM(5, 382) = 1910

GCD(5, 382) = ( 5 x 382 ) / 1910

= 5 / 382

= 5

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 455, 765, 382, 242 is 1
