Given numbers are 649, 744, 765, 623

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 623 are 7 x 89

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

Given numbers are 649, 744, 765, 623

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

Apply this formula for all numbers.

Step1:

LCM(649, 744) = 482856

GCD(649, 744) = ( 649 x 744 ) / 482856

= 649 / 744

= 649

Step2:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

Step3:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

So, Greatest Common Divisor of 649, 744, 765, 623 is 1
