Given numbers are 721, 805, 800, 940

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 805 are 5 x 7 x 23

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 940 are 2 x 2 x 5 x 47

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

Given numbers are 721, 805, 800, 940

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

Apply this formula for all numbers.

Step1:

LCM(721, 805) = 82915

GCD(721, 805) = ( 721 x 805 ) / 82915

= 721 / 805

= 721

Step2:

LCM(7, 800) = 5600

GCD(7, 800) = ( 7 x 800 ) / 5600

= 7 / 800

= 7

Step3:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

So, Greatest Common Divisor of 721, 805, 800, 940 is 1
