Given numbers are 126, 247, 446, 408

The list of prime factors of all numbers are

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 247 are 13 x 19

Prime factors of 446 are 2 x 223

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 126, 247, 446, 408

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

Apply this formula for all numbers.

Step1:

LCM(126, 247) = 31122

GCD(126, 247) = ( 126 x 247 ) / 31122

= 126 / 247

= 126

Step2:

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

= 1 / 446

= 1

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 126, 247, 446, 408 is 1
