Given numbers are 742, 723, 525, 438

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 723 are 3 x 241

Prime factors of 525 are 3 x 5 x 5 x 7

Prime factors of 438 are 2 x 3 x 73

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

Given numbers are 742, 723, 525, 438

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

Apply this formula for all numbers.

Step1:

LCM(742, 723) = 536466

GCD(742, 723) = ( 742 x 723 ) / 536466

= 742 / 723

= 742

Step2:

LCM(1, 525) = 525

GCD(1, 525) = ( 1 x 525 ) / 525

= 1 / 525

= 1

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 742, 723, 525, 438 is 1
