Greatest Common Factor
We found the factors 872,147 . The biggest common factor number is the GCF number.
So the greatest common factor 872,147 is 1.
Lets's calculate LCM of 688,674
2 | 688, 674 |
344, 337 |
∴ So the LCM of the given numbers is 2 x 344 x 337 = 231856
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/231856
Therefore, the GCF of Fractions 872/688,147/674 is 1/231856
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 688,674 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(688,674) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(688,674) x common factors =2 x 1 = 2
LCM(688,674) = ( 688 × 674 ) / 2
LCM(688,674) = 463712 / 2
LCM(688,674) = 231856
