So the greatest common factor 680,716,834 is 2.
Lets's calculate LCM of 820,919,372
2 | 820, 919, 372 |
2 | 410, 919, 186 |
205, 919, 93 |
∴ So the LCM of the given numbers is 2 x 2 x 205 x 919 x 93 = 70082940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/70082940
Therefore, the GCF of Fractions 680/820,716/919,834/372 is 2/70082940
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 820,919,372 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,919,372) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(820,919,372) x common factors =1 x 4 = 4
LCM(820,919,372) = ( 820 × 919 × 372 ) / 4
LCM(820,919,372) = 280331760 / 4
LCM(820,919,372) = 70082940
