Given numbers are 420, 455, 914, 339

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 455 are 5 x 7 x 13

Prime factors of 914 are 2 x 457

Prime factors of 339 are 3 x 113

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

Given numbers are 420, 455, 914, 339

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

Apply this formula for all numbers.

Step1:

LCM(420, 455) = 5460

GCD(420, 455) = ( 420 x 455 ) / 5460

= 420 / 455

= 420

Step2:

LCM(35, 914) = 31990

GCD(35, 914) = ( 35 x 914 ) / 31990

= 35 / 914

= 35

Step3:

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

= 1 / 339

= 1

So, Greatest Common Divisor of 420, 455, 914, 339 is 1
