Given numbers are 530, 436, 742, 203

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 436 are 2 x 2 x 109

Prime factors of 742 are 2 x 7 x 53

Prime factors of 203 are 7 x 29

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

Given numbers are 530, 436, 742, 203

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

Apply this formula for all numbers.

Step1:

LCM(530, 436) = 115540

GCD(530, 436) = ( 530 x 436 ) / 115540

= 530 / 436

= 530

Step2:

LCM(2, 742) = 742

GCD(2, 742) = ( 2 x 742 ) / 742

= 2 / 742

= 2

Step3:

LCM(2, 203) = 406

GCD(2, 203) = ( 2 x 203 ) / 406

= 2 / 203

= 2

So, Greatest Common Divisor of 530, 436, 742, 203 is 1
