Given numbers are 801, 877, 620, 721

The list of prime factors of all numbers are

Prime factors of 801 are 3 x 3 x 89

Prime factors of 877 are 877

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 721 are 7 x 103

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

Given numbers are 801, 877, 620, 721

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

Apply this formula for all numbers.

Step1:

LCM(801, 877) = 702477

GCD(801, 877) = ( 801 x 877 ) / 702477

= 801 / 877

= 801

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 721) = 721

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

= 1 / 721

= 1

So, Greatest Common Divisor of 801, 877, 620, 721 is 1
