Greatest Common Factor
We found the factors 425,137 . The biggest common factor number is the GCF number.
So the greatest common factor 425,137 is 1.
Lets's calculate LCM of 65,645
5 | 65, 645 |
13, 129 |
∴ So the LCM of the given numbers is 5 x 13 x 129 = 8385
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8385
Therefore, the GCF of Fractions 425/65,137/645 is 1/8385
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 65,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,645) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(65,645) x common factors =5 x 1 = 5
LCM(65,645) = ( 65 × 645 ) / 5
LCM(65,645) = 41925 / 5
LCM(65,645) = 8385
