Greatest Common Divisior
We found the divisors of 79, 840, 862, 622 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 79, 840, 862, 622 is 1.
Therefore, GCD of numbers 79, 840, 862, 622 is 1
Given Input Data is 79, 840, 862, 622
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 79 is 79
Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7
Prime Factorization of 862 is 2 x 431
Prime Factorization of 622 is 2 x 311
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(79, 840) = 66360
GCD(79, 840) = ( 79 x 840 ) / 66360
GCD(79, 840) = 66360 / 66360
GCD(79, 840) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 862
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 862) = 862
GCD(1, 862) = ( 1 x 862 ) / 862
GCD(1, 862) = 862 / 862
GCD(1, 862) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 622
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 622) = 622
GCD(1, 622) = ( 1 x 622 ) / 622
GCD(1, 622) = 622 / 622
GCD(1, 622) = 1
GCD of 79, 840, 862, 622 is 1
