Lets's calculate GCF of 837,225
3 | 837, 225 |
3 | 279, 75 |
93, 25 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Now, list down the factors of 837
:1,3,9,27,31,93,279,837
Now, list down the factors of 225
:1,3,5,9,15,25,45,75,225
Greatest Common Factor
We found the factors 837,225 . The biggest common factor number is the GCF number.
So the greatest common factor 837,225 is 9.
Lets's calculate LCM of 31,672
Given numbers has no common factors except 1. So, there LCM is their product i.e 20832
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/20832
Therefore, the GCF of Fractions 837/31,225/672 is 9/20832
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 31,672 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,672) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,672) x common factors =1 x 1 = 1
LCM(31,672) = ( 31 × 672 ) / 1
LCM(31,672) = 20832 / 1
LCM(31,672) = 20832
