Given numbers are 603, 871, 690, 805

The list of prime factors of all numbers are

Prime factors of 603 are 3 x 3 x 67

Prime factors of 871 are 13 x 67

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 603, 871, 690, 805

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

Apply this formula for all numbers.

Step1:

LCM(603, 871) = 7839

GCD(603, 871) = ( 603 x 871 ) / 7839

= 603 / 871

= 603

Step2:

LCM(67, 690) = 46230

GCD(67, 690) = ( 67 x 690 ) / 46230

= 67 / 690

= 67

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 603, 871, 690, 805 is 1
