Lets's calculate GCF of 125,725
5 | 125, 725 |
5 | 25, 145 |
5, 29 |
∴ So the GCF of the given numbers is 5 x 5 = 25
Now, list down the factors of 125
:1,5,25,125
Now, list down the factors of 725
:1,5,25,29,145,725
Greatest Common Factor
We found the factors 125,725 . The biggest common factor number is the GCF number.
So the greatest common factor 125,725 is 25.
Lets's calculate LCM of 671,644
Given numbers has no common factors except 1. So, there LCM is their product i.e 432124
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 25/432124
Therefore, the GCF of Fractions 125/671,725/644 is 25/432124
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 671,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(671,644) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(671,644) x common factors =1 x 1 = 1
LCM(671,644) = ( 671 × 644 ) / 1
LCM(671,644) = 432124 / 1
LCM(671,644) = 432124
