Given numbers are 428, 361, 684, 254

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 361 are 19 x 19

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 254 are 2 x 127

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

Given numbers are 428, 361, 684, 254

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

Apply this formula for all numbers.

Step1:

LCM(428, 361) = 154508

GCD(428, 361) = ( 428 x 361 ) / 154508

= 428 / 361

= 428

Step2:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 428, 361, 684, 254 is 1
