Given numbers are 154, 648, 753, 749

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

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

Prime factors of 753 are 3 x 251

Prime factors of 749 are 7 x 107

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

Given numbers are 154, 648, 753, 749

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

Apply this formula for all numbers.

Step1:

LCM(154, 648) = 49896

GCD(154, 648) = ( 154 x 648 ) / 49896

= 154 / 648

= 154

Step2:

LCM(2, 753) = 1506

GCD(2, 753) = ( 2 x 753 ) / 1506

= 2 / 753

= 2

Step3:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

So, Greatest Common Divisor of 154, 648, 753, 749 is 1
