We found the divisors of 730, 861, 65, 907 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 730, 861, 65, 907 is 1.

Therefore, GCD of numbers 730, 861, 65, 907 is 1

Given Input Data is 730, 861, 65, 907

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 730 is 2 x 5 x 73

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 65 is 5 x 13

Prime Factorization of 907 is 907

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(730, 861) = 628530

GCD(730, 861) = ( 730 x 861 ) / 628530

GCD(730, 861) = 628530 / 628530

GCD(730, 861) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 65

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

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

GCD(1, 65) = 65 / 65

GCD(1, 65) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 907

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

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

GCD(1, 907) = 907 / 907

GCD(1, 907) = 1

GCD of 730, 861, 65, 907 is 1
