Given numbers are 406, 305, 663, 196

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 305 are 5 x 61

Prime factors of 663 are 3 x 13 x 17

Prime factors of 196 are 2 x 2 x 7 x 7

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

Given numbers are 406, 305, 663, 196

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

Apply this formula for all numbers.

Step1:

LCM(406, 305) = 123830

GCD(406, 305) = ( 406 x 305 ) / 123830

= 406 / 305

= 406

Step2:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

Step3:

LCM(1, 196) = 196

GCD(1, 196) = ( 1 x 196 ) / 196

= 1 / 196

= 1

So, Greatest Common Divisor of 406, 305, 663, 196 is 1
