Given numbers are 428, 623, 485, 684

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 623 are 7 x 89

Prime factors of 485 are 5 x 97

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

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

Given numbers are 428, 623, 485, 684

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

Apply this formula for all numbers.

Step1:

LCM(428, 623) = 266644

GCD(428, 623) = ( 428 x 623 ) / 266644

= 428 / 623

= 428

Step2:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

Step3:

LCM(1, 684) = 684

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

= 1 / 684

= 1

So, Greatest Common Divisor of 428, 623, 485, 684 is 1
