Given numbers are 820, 703, 721, 577

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 703 are 19 x 37

Prime factors of 721 are 7 x 103

Prime factors of 577 are 577

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

Given numbers are 820, 703, 721, 577

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

Apply this formula for all numbers.

Step1:

LCM(820, 703) = 576460

GCD(820, 703) = ( 820 x 703 ) / 576460

= 820 / 703

= 820

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 577) = 577

GCD(1, 577) = ( 1 x 577 ) / 577

= 1 / 577

= 1

So, Greatest Common Divisor of 820, 703, 721, 577 is 1
