Given numbers are 428, 427, 350, 280

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 427 are 7 x 61

Prime factors of 350 are 2 x 5 x 5 x 7

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 428, 427, 350, 280

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

Apply this formula for all numbers.

Step1:

LCM(428, 427) = 182756

GCD(428, 427) = ( 428 x 427 ) / 182756

= 428 / 427

= 428

Step2:

LCM(1, 350) = 350

GCD(1, 350) = ( 1 x 350 ) / 350

= 1 / 350

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 428, 427, 350, 280 is 1
