Given numbers are 648, 998, 805, 961

The list of prime factors of all numbers are

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

Prime factors of 998 are 2 x 499

Prime factors of 805 are 5 x 7 x 23

Prime factors of 961 are 31 x 31

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

Given numbers are 648, 998, 805, 961

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

Apply this formula for all numbers.

Step1:

LCM(648, 998) = 323352

GCD(648, 998) = ( 648 x 998 ) / 323352

= 648 / 998

= 648

Step2:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

Step3:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

So, Greatest Common Divisor of 648, 998, 805, 961 is 1
