Lets's calculate LCM of 12,7640
2 | 12, 7640 |
2 | 6, 3820 |
3, 1910 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 1910 = 22920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/22920
Therefore, the GCF of Fractions 849/12,975/7640 is 3/22920
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 12,7640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,7640) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(12,7640) x common factors =4 x 1 = 4
LCM(12,7640) = ( 12 × 7640 ) / 4
LCM(12,7640) = 91680 / 4
LCM(12,7640) = 22920
