Greatest Common Factor
We found the factors 2155,5135 . The biggest common factor number is the GCF number.
So the greatest common factor 2155,5135 is 5.
Lets's calculate LCM of 725,715
5 | 725, 715 |
145, 143 |
∴ So the LCM of the given numbers is 5 x 145 x 143 = 103675
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/103675
Therefore, the GCF of Fractions 2155/725,5135/715 is 5/103675
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 725,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(725,715) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(725,715) x common factors =5 x 1 = 5
LCM(725,715) = ( 725 × 715 ) / 5
LCM(725,715) = 518375 / 5
LCM(725,715) = 103675
