Given numbers are 648, 931, 221, 475

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 931 are 7 x 7 x 19

Prime factors of 221 are 13 x 17

Prime factors of 475 are 5 x 5 x 19

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

Given numbers are 648, 931, 221, 475

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

Apply this formula for all numbers.

Step1:

LCM(648, 931) = 603288

GCD(648, 931) = ( 648 x 931 ) / 603288

= 648 / 931

= 648

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

So, Greatest Common Divisor of 648, 931, 221, 475 is 1
