1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
Greatest Common Divisior
We found the divisors of 620, 895, 841, 980 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 620, 895, 841, 980 is 1.
Therefore, GCD of numbers 620, 895, 841, 980 is 1
Given Input Data is 620, 895, 841, 980
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 620 is 2 x 2 x 5 x 31
Prime Factorization of 895 is 5 x 179
Prime Factorization of 841 is 29 x 29
Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7
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(620, 895) = 110980
GCD(620, 895) = ( 620 x 895 ) / 110980
GCD(620, 895) = 554900 / 110980
GCD(620, 895) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 841
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 841) = 4205
GCD(5, 841) = ( 5 x 841 ) / 4205
GCD(5, 841) = 4205 / 4205
GCD(5, 841) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 980
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
GCD(1, 980) = 980 / 980
GCD(1, 980) = 1
GCD of 620, 895, 841, 980 is 1
