Given numbers are 731, 669, 742, 745

The list of prime factors of all numbers are

Prime factors of 731 are 17 x 43

Prime factors of 669 are 3 x 223

Prime factors of 742 are 2 x 7 x 53

Prime factors of 745 are 5 x 149

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

Given numbers are 731, 669, 742, 745

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

Apply this formula for all numbers.

Step1:

LCM(731, 669) = 489039

GCD(731, 669) = ( 731 x 669 ) / 489039

= 731 / 669

= 731

Step2:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 731, 669, 742, 745 is 1
