Given numbers are 455, 265, 402, 349

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 265 are 5 x 53

Prime factors of 402 are 2 x 3 x 67

Prime factors of 349 are 349

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

Given numbers are 455, 265, 402, 349

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

Apply this formula for all numbers.

Step1:

LCM(455, 265) = 24115

GCD(455, 265) = ( 455 x 265 ) / 24115

= 455 / 265

= 455

Step2:

LCM(5, 402) = 2010

GCD(5, 402) = ( 5 x 402 ) / 2010

= 5 / 402

= 5

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 455, 265, 402, 349 is 1
