Given numbers are 417, 213, 648, 961

The list of prime factors of all numbers are

Prime factors of 417 are 3 x 139

Prime factors of 213 are 3 x 71

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

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 417, 213, 648, 961

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

Apply this formula for all numbers.

Step1:

LCM(417, 213) = 29607

GCD(417, 213) = ( 417 x 213 ) / 29607

= 417 / 213

= 417

Step2:

LCM(3, 648) = 648

GCD(3, 648) = ( 3 x 648 ) / 648

= 3 / 648

= 3

Step3:

LCM(3, 961) = 2883

GCD(3, 961) = ( 3 x 961 ) / 2883

= 3 / 961

= 3

So, Greatest Common Divisor of 417, 213, 648, 961 is 1
