Greatest Common Factor
We found the factors 712,856 . The biggest common factor number is the GCF number.
So the greatest common factor 712,856 is 8.
Lets's calculate LCM of 700,782
2 | 700, 782 |
350, 391 |
∴ So the LCM of the given numbers is 2 x 350 x 391 = 273700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/273700
Therefore, the GCF of Fractions 712/700,856/782 is 8/273700
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 700,782 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(700,782) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(700,782) x common factors =2 x 1 = 2
LCM(700,782) = ( 700 × 782 ) / 2
LCM(700,782) = 547400 / 2
LCM(700,782) = 273700
