Given numbers are 649, 365, 648, 921

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 365 are 5 x 73

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

Prime factors of 921 are 3 x 307

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

Given numbers are 649, 365, 648, 921

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

Apply this formula for all numbers.

Step1:

LCM(649, 365) = 236885

GCD(649, 365) = ( 649 x 365 ) / 236885

= 649 / 365

= 649

Step2:

LCM(1, 648) = 648

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

= 1 / 648

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 649, 365, 648, 921 is 1
