Given numbers are 268, 447, 455, 415

The list of prime factors of all numbers are

Prime factors of 268 are 2 x 2 x 67

Prime factors of 447 are 3 x 149

Prime factors of 455 are 5 x 7 x 13

Prime factors of 415 are 5 x 83

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

Given numbers are 268, 447, 455, 415

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

Apply this formula for all numbers.

Step1:

LCM(268, 447) = 119796

GCD(268, 447) = ( 268 x 447 ) / 119796

= 268 / 447

= 268

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

So, Greatest Common Divisor of 268, 447, 455, 415 is 1
