Given numbers are 742, 503, 168, 665

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 503 are 503

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 742, 503, 168, 665

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

Apply this formula for all numbers.

Step1:

LCM(742, 503) = 373226

GCD(742, 503) = ( 742 x 503 ) / 373226

= 742 / 503

= 742

Step2:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 742, 503, 168, 665 is 1
