Given numbers are 603, 721, 570, 921

The list of prime factors of all numbers are

Prime factors of 603 are 3 x 3 x 67

Prime factors of 721 are 7 x 103

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 921 are 3 x 307

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

Given numbers are 603, 721, 570, 921

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

Apply this formula for all numbers.

Step1:

LCM(603, 721) = 434763

GCD(603, 721) = ( 603 x 721 ) / 434763

= 603 / 721

= 603

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 603, 721, 570, 921 is 1
