So the greatest common factor 770,498 is 2.
Lets's calculate LCM of 847,511
7 | 847, 511 |
121, 73 |
∴ So the LCM of the given numbers is 7 x 121 x 73 = 61831
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/61831
Therefore, the GCF of Fractions 770/847,498/511 is 2/61831
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 847,511 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(847,511) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(847,511) x common factors =7 x 1 = 7
LCM(847,511) = ( 847 × 511 ) / 7
LCM(847,511) = 432817 / 7
LCM(847,511) = 61831
