So the greatest common factor 82,67,994 is 1.
Lets's calculate LCM of 648,724,781
2 | 648, 724, 781 |
2 | 324, 362, 781 |
162, 181, 781 |
∴ So the LCM of the given numbers is 2 x 2 x 162 x 181 x 781 = 91601928
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/91601928
Therefore, the GCF of Fractions 82/648,67/724,994/781 is 1/91601928
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 648,724,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(648,724,781) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(648,724,781) x common factors =1 x 4 = 4
LCM(648,724,781) = ( 648 × 724 × 781 ) / 4
LCM(648,724,781) = 366407712 / 4
LCM(648,724,781) = 91601928
