Given numbers are 575, 744, 680, 645

The list of prime factors of all numbers are

Prime factors of 575 are 5 x 5 x 23

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

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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 575, 744, 680, 645

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

Apply this formula for all numbers.

Step1:

LCM(575, 744) = 427800

GCD(575, 744) = ( 575 x 744 ) / 427800

= 575 / 744

= 575

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

Step3:

LCM(1, 645) = 645

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

= 1 / 645

= 1

So, Greatest Common Divisor of 575, 744, 680, 645 is 1
