Given numbers are 690, 871, 768, 481

The list of prime factors of all numbers are

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

Prime factors of 871 are 13 x 67

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 481 are 13 x 37

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

Given numbers are 690, 871, 768, 481

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

Apply this formula for all numbers.

Step1:

LCM(690, 871) = 600990

GCD(690, 871) = ( 690 x 871 ) / 600990

= 690 / 871

= 690

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

= 1 / 481

= 1

So, Greatest Common Divisor of 690, 871, 768, 481 is 1
