Given numbers are 648, 520, 653, 843

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 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 653 are 653

Prime factors of 843 are 3 x 281

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

Given numbers are 648, 520, 653, 843

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

Apply this formula for all numbers.

Step1:

LCM(648, 520) = 42120

GCD(648, 520) = ( 648 x 520 ) / 42120

= 648 / 520

= 648

Step2:

LCM(8, 653) = 5224

GCD(8, 653) = ( 8 x 653 ) / 5224

= 8 / 653

= 8

Step3:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

So, Greatest Common Divisor of 648, 520, 653, 843 is 1
