Lets's calculate GCF of 870,406
2 | 870, 406 |
29 | 435, 203 |
15, 7 |
∴ So the GCF of the given numbers is 2 x 29 = 58
Now, list down the factors of 870
:1,2,3,5,6,10,15,29,30,58,87,145,174,290,435,870
Now, list down the factors of 406
:1,2,7,14,29,58,203,406
Greatest Common Factor
We found the factors 870,406 . The biggest common factor number is the GCF number.
So the greatest common factor 870,406 is 58.
Lets's calculate LCM of 53,791
Given numbers has no common factors except 1. So, there LCM is their product i.e 41923
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 58/41923
Therefore, the GCF of Fractions 870/53,406/791 is 58/41923
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 53,791 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(53,791) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(53,791) x common factors =1 x 1 = 1
LCM(53,791) = ( 53 × 791 ) / 1
LCM(53,791) = 41923 / 1
LCM(53,791) = 41923
