Make use of GCD Calculator to determine the Greatest Common Divisor of 690, 423, 87, 283 i.e. 1 largest integer that divides all the numbers equally.
GCD of 690, 423, 87, 283 is 1
GCD(690, 423, 87, 283) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 690, 423, 87, 283 is 1
GCD(690, 423, 87, 283) = 1
Given Input numbers are 690, 423, 87, 283
To find the GCD of numbers using factoring list out all the divisors of each number

1, 283
Greatest Common Divisior
We found the divisors of 690, 423, 87, 283 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 690, 423, 87, 283 is 1.
Therefore, GCD of numbers 690, 423, 87, 283 is 1
Given Input Data is 690, 423, 87, 283
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 690 is 2 x 3 x 5 x 23
Prime Factorization of 423 is 3 x 3 x 47
Prime Factorization of 87 is 3 x 29
Prime Factorization of 283 is 283
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(690, 423) = 97290
GCD(690, 423) = ( 690 x 423 ) / 97290
GCD(690, 423) = 291870 / 97290
GCD(690, 423) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 87
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 87) = 87
GCD(3, 87) = ( 3 x 87 ) / 87
GCD(3, 87) = 261 / 87
GCD(3, 87) = 3
Step3:
Here we consider the GCD from the above i.e. 3 as first number and the next as 283
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 283) = 849
GCD(3, 283) = ( 3 x 283 ) / 849
GCD(3, 283) = 849 / 849
GCD(3, 283) = 1
GCD of 690, 423, 87, 283 is 1
