Given numbers are 660, 504, 417, 245

The list of prime factors of all numbers are

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

Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7

Prime factors of 417 are 3 x 139

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 660, 504, 417, 245

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

Apply this formula for all numbers.

Step1:

LCM(660, 504) = 27720

GCD(660, 504) = ( 660 x 504 ) / 27720

= 660 / 504

= 660

Step2:

LCM(12, 417) = 1668

GCD(12, 417) = ( 12 x 417 ) / 1668

= 12 / 417

= 12

Step3:

LCM(3, 245) = 735

GCD(3, 245) = ( 3 x 245 ) / 735

= 3 / 245

= 3

So, Greatest Common Divisor of 660, 504, 417, 245 is 1
