Given numbers are 428, 654, 406, 613

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 654 are 2 x 3 x 109

Prime factors of 406 are 2 x 7 x 29

Prime factors of 613 are 613

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

Given numbers are 428, 654, 406, 613

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

Apply this formula for all numbers.

Step1:

LCM(428, 654) = 139956

GCD(428, 654) = ( 428 x 654 ) / 139956

= 428 / 654

= 428

Step2:

LCM(2, 406) = 406

GCD(2, 406) = ( 2 x 406 ) / 406

= 2 / 406

= 2

Step3:

LCM(2, 613) = 1226

GCD(2, 613) = ( 2 x 613 ) / 1226

= 2 / 613

= 2

So, Greatest Common Divisor of 428, 654, 406, 613 is 1
