Given numbers are 648, 924, 758, 665

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 924 are 2 x 2 x 3 x 7 x 11

Prime factors of 758 are 2 x 379

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 648, 924, 758, 665

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

Apply this formula for all numbers.

Step1:

LCM(648, 924) = 49896

GCD(648, 924) = ( 648 x 924 ) / 49896

= 648 / 924

= 648

Step2:

LCM(12, 758) = 4548

GCD(12, 758) = ( 12 x 758 ) / 4548

= 12 / 758

= 12

Step3:

LCM(2, 665) = 1330

GCD(2, 665) = ( 2 x 665 ) / 1330

= 2 / 665

= 2

So, Greatest Common Divisor of 648, 924, 758, 665 is 1
