Given numbers are 674, 245, 648, 646

The list of prime factors of all numbers are

Prime factors of 674 are 2 x 337

Prime factors of 245 are 5 x 7 x 7

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

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 674, 245, 648, 646

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

Apply this formula for all numbers.

Step1:

LCM(674, 245) = 165130

GCD(674, 245) = ( 674 x 245 ) / 165130

= 674 / 245

= 674

Step2:

LCM(1, 648) = 648

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

= 1 / 648

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 674, 245, 648, 646 is 1
