Given numbers are 345, 237, 972, 409

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 237 are 3 x 79

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 409 are 409

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

Given numbers are 345, 237, 972, 409

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

Apply this formula for all numbers.

Step1:

LCM(345, 237) = 27255

GCD(345, 237) = ( 345 x 237 ) / 27255

= 345 / 237

= 345

Step2:

LCM(3, 972) = 972

GCD(3, 972) = ( 3 x 972 ) / 972

= 3 / 972

= 3

Step3:

LCM(3, 409) = 1227

GCD(3, 409) = ( 3 x 409 ) / 1227

= 3 / 409

= 3

So, Greatest Common Divisor of 345, 237, 972, 409 is 1
