Given numbers are 519, 728, 945, 245

The list of prime factors of all numbers are

Prime factors of 519 are 3 x 173

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

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 519, 728, 945, 245

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

Apply this formula for all numbers.

Step1:

LCM(519, 728) = 377832

GCD(519, 728) = ( 519 x 728 ) / 377832

= 519 / 728

= 519

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 245) = 245

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

= 1 / 245

= 1

So, Greatest Common Divisor of 519, 728, 945, 245 is 1
