Given numbers are 305, 407, 66, 222

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 407 are 11 x 37

Prime factors of 66 are 2 x 3 x 11

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 305, 407, 66, 222

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

Apply this formula for all numbers.

Step1:

LCM(305, 407) = 124135

GCD(305, 407) = ( 305 x 407 ) / 124135

= 305 / 407

= 305

Step2:

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

= 1 / 66

= 1

Step3:

LCM(1, 222) = 222

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

= 1 / 222

= 1

So, Greatest Common Divisor of 305, 407, 66, 222 is 1
