The list of prime factors of all numbers are

Prime factors of 429 are 3 x 11 x 13

Prime factors of 974 are 2 x 487

Prime factors of 406 are 2 x 7 x 29

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 429, 974, 406, 648

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

Apply this formula for all numbers.

Step1:

LCM(429, 974) = 417846

GCD(429, 974) = ( 429 x 974 ) / 417846

= 429 / 974

= 429

Step2:

LCM(1, 406) = 406

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

= 1 / 406

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 429, 974, 406, 648 is 1
