Given numbers are 744, 155, 845, 645

The list of prime factors of all numbers are

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

Prime factors of 155 are 5 x 31

Prime factors of 845 are 5 x 13 x 13

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 744, 155, 845, 645

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

Apply this formula for all numbers.

Step1:

LCM(744, 155) = 3720

GCD(744, 155) = ( 744 x 155 ) / 3720

= 744 / 155

= 744

Step2:

LCM(31, 845) = 26195

GCD(31, 845) = ( 31 x 845 ) / 26195

= 31 / 845

= 31

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 744, 155, 845, 645 is 1
