Given numbers are 721, 840, 885, 581

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 885 are 3 x 5 x 59

Prime factors of 581 are 7 x 83

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

Given numbers are 721, 840, 885, 581

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

Apply this formula for all numbers.

Step1:

LCM(721, 840) = 86520

GCD(721, 840) = ( 721 x 840 ) / 86520

= 721 / 840

= 721

Step2:

LCM(7, 885) = 6195

GCD(7, 885) = ( 7 x 885 ) / 6195

= 7 / 885

= 7

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 721, 840, 885, 581 is 1
