Given numbers are 742, 239, 731, 440

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 239 are 239

Prime factors of 731 are 17 x 43

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 742, 239, 731, 440

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

Apply this formula for all numbers.

Step1:

LCM(742, 239) = 177338

GCD(742, 239) = ( 742 x 239 ) / 177338

= 742 / 239

= 742

Step2:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 742, 239, 731, 440 is 1
