Given numbers are 697, 409, 260, 648

The list of prime factors of all numbers are

Prime factors of 697 are 17 x 41

Prime factors of 409 are 409

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 697, 409, 260, 648

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

Apply this formula for all numbers.

Step1:

LCM(697, 409) = 285073

GCD(697, 409) = ( 697 x 409 ) / 285073

= 697 / 409

= 697

Step2:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 697, 409, 260, 648 is 1
