Given numbers are 245, 945, 163, 819

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 163 are 163

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 245, 945, 163, 819

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

Apply this formula for all numbers.

Step1:

LCM(245, 945) = 6615

GCD(245, 945) = ( 245 x 945 ) / 6615

= 245 / 945

= 245

Step2:

LCM(35, 163) = 5705

GCD(35, 163) = ( 35 x 163 ) / 5705

= 35 / 163

= 35

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 245, 945, 163, 819 is 1
