Given numbers are 126, 870, 409, 324

The list of prime factors of all numbers are

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

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 409 are 409

Prime factors of 324 are 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 126, 870, 409, 324

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

Apply this formula for all numbers.

Step1:

LCM(126, 870) = 18270

GCD(126, 870) = ( 126 x 870 ) / 18270

= 126 / 870

= 126

Step2:

LCM(6, 409) = 2454

GCD(6, 409) = ( 6 x 409 ) / 2454

= 6 / 409

= 6

Step3:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

So, Greatest Common Divisor of 126, 870, 409, 324 is 1
