Given numbers are 428, 507, 406, 392

The list of prime factors of all numbers are

Prime factors of 428 are 2 x 2 x 107

Prime factors of 507 are 3 x 13 x 13

Prime factors of 406 are 2 x 7 x 29

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 428, 507, 406, 392

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

Apply this formula for all numbers.

Step1:

LCM(428, 507) = 216996

GCD(428, 507) = ( 428 x 507 ) / 216996

= 428 / 507

= 428

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 428, 507, 406, 392 is 1
