Make use of GCD Calculator to determine the Greatest Common Divisor of 850, 639, 12, 149 i.e. 1 largest integer that divides all the numbers equally.
GCD of 850, 639, 12, 149 is 1
GCD(850, 639, 12, 149) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 850, 639, 12, 149 is 1
GCD(850, 639, 12, 149) = 1
Given Input numbers are 850, 639, 12, 149
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 850

1, 2, 3, 4, 6, 12
Divisors of 149
List of positive integer divisors of 149 that divides 149 without a remainder.
1, 149
Greatest Common Divisior
We found the divisors of 850, 639, 12, 149 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 850, 639, 12, 149 is 1.
Therefore, GCD of numbers 850, 639, 12, 149 is 1
Given Input Data is 850, 639, 12, 149
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 850 is 2 x 5 x 5 x 17
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 12 is 2 x 2 x 3
Prime Factorization of 149 is 149
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(850, 639) = 543150
GCD(850, 639) = ( 850 x 639 ) / 543150
GCD(850, 639) = 543150 / 543150
GCD(850, 639) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 12
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 12) = 12
GCD(1, 12) = ( 1 x 12 ) / 12
GCD(1, 12) = 12 / 12
GCD(1, 12) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 149
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 149) = 149
GCD(1, 149) = ( 1 x 149 ) / 149
GCD(1, 149) = 149 / 149
GCD(1, 149) = 1
GCD of 850, 639, 12, 149 is 1
