Greatest Common Factor
We found the factors 860,138 . The biggest common factor number is the GCF number.
So the greatest common factor 860,138 is 2.
Lets's calculate LCM of 774,650
2 | 774, 650 |
387, 325 |
∴ So the LCM of the given numbers is 2 x 387 x 325 = 251550
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/251550
Therefore, the GCF of Fractions 860/774,138/650 is 2/251550
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 774,650 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(774,650) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(774,650) x common factors =2 x 1 = 2
LCM(774,650) = ( 774 × 650 ) / 2
LCM(774,650) = 503100 / 2
LCM(774,650) = 251550
