Given numbers are 406, 660, 245, 318

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 245 are 5 x 7 x 7

Prime factors of 318 are 2 x 3 x 53

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

Given numbers are 406, 660, 245, 318

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

Apply this formula for all numbers.

Step1:

LCM(406, 660) = 133980

GCD(406, 660) = ( 406 x 660 ) / 133980

= 406 / 660

= 406

Step2:

LCM(2, 245) = 490

GCD(2, 245) = ( 2 x 245 ) / 490

= 2 / 245

= 2

Step3:

LCM(1, 318) = 318

GCD(1, 318) = ( 1 x 318 ) / 318

= 1 / 318

= 1

So, Greatest Common Divisor of 406, 660, 245, 318 is 1
