Given numbers are 342, 644, 409, 222

The list of prime factors of all numbers are

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 409 are 409

Prime factors of 222 are 2 x 3 x 37

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

Given numbers are 342, 644, 409, 222

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

Apply this formula for all numbers.

Step1:

LCM(342, 644) = 110124

GCD(342, 644) = ( 342 x 644 ) / 110124

= 342 / 644

= 342

Step2:

LCM(2, 409) = 818

GCD(2, 409) = ( 2 x 409 ) / 818

= 2 / 409

= 2

Step3:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

So, Greatest Common Divisor of 342, 644, 409, 222 is 1
