Given numbers are 407, 631, 433, 218

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 631 are 631

Prime factors of 433 are 433

Prime factors of 218 are 2 x 109

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

Given numbers are 407, 631, 433, 218

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

Apply this formula for all numbers.

Step1:

LCM(407, 631) = 256817

GCD(407, 631) = ( 407 x 631 ) / 256817

= 407 / 631

= 407

Step2:

LCM(1, 433) = 433

GCD(1, 433) = ( 1 x 433 ) / 433

= 1 / 433

= 1

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 407, 631, 433, 218 is 1
