The list of prime factors of all numbers are

Prime factors of 829 are 829

Prime factors of 740 are 2 x 2 x 5 x 37

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

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

Given numbers are 829, 740, 245, 648

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

Apply this formula for all numbers.

Step1:

LCM(829, 740) = 613460

GCD(829, 740) = ( 829 x 740 ) / 613460

= 829 / 740

= 829

Step2:

LCM(1, 245) = 245

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

= 1 / 245

= 1

Step3:

LCM(1, 648) = 648

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

= 1 / 648

= 1

So, Greatest Common Divisor of 829, 740, 245, 648 is 1
