1, 479
Greatest Common Divisior
We found the divisors of 715, 780, 611, 479 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 715, 780, 611, 479 is 1.
Therefore, GCD of numbers 715, 780, 611, 479 is 1
Given Input Data is 715, 780, 611, 479
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 715 is 5 x 11 x 13
Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13
Prime Factorization of 611 is 13 x 47
Prime Factorization of 479 is 479
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(715, 780) = 8580
GCD(715, 780) = ( 715 x 780 ) / 8580
GCD(715, 780) = 557700 / 8580
GCD(715, 780) = 65
Step2:
Here we consider the GCD from the above i.e. 65 as first number and the next as 611
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(65, 611) = 3055
GCD(65, 611) = ( 65 x 611 ) / 3055
GCD(65, 611) = 39715 / 3055
GCD(65, 611) = 13
Step3:
Here we consider the GCD from the above i.e. 13 as first number and the next as 479
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(13, 479) = 6227
GCD(13, 479) = ( 13 x 479 ) / 6227
GCD(13, 479) = 6227 / 6227
GCD(13, 479) = 1
GCD of 715, 780, 611, 479 is 1
