Make use of GCD Calculator to determine the Greatest Common Divisor of 210, 127, 490, 655 i.e. 1 largest integer that divides all the numbers equally.
GCD of 210, 127, 490, 655 is 1
GCD(210, 127, 490, 655) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 210, 127, 490, 655 is 1
GCD(210, 127, 490, 655) = 1
Given Input numbers are 210, 127, 490, 655
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 131, 655
Greatest Common Divisior
We found the divisors of 210, 127, 490, 655 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 210, 127, 490, 655 is 1.
Therefore, GCD of numbers 210, 127, 490, 655 is 1
Given Input Data is 210, 127, 490, 655
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 210 is 2 x 3 x 5 x 7
Prime Factorization of 127 is 127
Prime Factorization of 490 is 2 x 5 x 7 x 7
Prime Factorization of 655 is 5 x 131
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(210, 127) = 26670
GCD(210, 127) = ( 210 x 127 ) / 26670
GCD(210, 127) = 26670 / 26670
GCD(210, 127) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 490
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
GCD(1, 490) = 490 / 490
GCD(1, 490) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 655
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
GCD(1, 655) = 655 / 655
GCD(1, 655) = 1
GCD of 210, 127, 490, 655 is 1
