Greatest Common Factor
We found the factors 781,265 . The biggest common factor number is the GCF number.
So the greatest common factor 781,265 is 1.
Lets's calculate LCM of 84,218
2 | 84, 218 |
42, 109 |
∴ So the LCM of the given numbers is 2 x 42 x 109 = 9156
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9156
Therefore, the GCF of Fractions 781/84,265/218 is 1/9156
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 84,218 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,218) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(84,218) x common factors =2 x 1 = 2
LCM(84,218) = ( 84 × 218 ) / 2
LCM(84,218) = 18312 / 2
LCM(84,218) = 9156
