Given numbers are 420, 326, 463, 245

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 326 are 2 x 163

Prime factors of 463 are 463

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 420, 326, 463, 245

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

Apply this formula for all numbers.

Step1:

LCM(420, 326) = 68460

GCD(420, 326) = ( 420 x 326 ) / 68460

= 420 / 326

= 420

Step2:

LCM(2, 463) = 926

GCD(2, 463) = ( 2 x 463 ) / 926

= 2 / 463

= 2

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 420, 326, 463, 245 is 1
