Given numbers are 721, 372, 861, 105

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 861 are 3 x 7 x 41

Prime factors of 105 are 3 x 5 x 7

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

Given numbers are 721, 372, 861, 105

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

Apply this formula for all numbers.

Step1:

LCM(721, 372) = 268212

GCD(721, 372) = ( 721 x 372 ) / 268212

= 721 / 372

= 721

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

So, Greatest Common Divisor of 721, 372, 861, 105 is 1
