Lets's calculate LCM of 246,840
2 | 246, 840 |
3 | 123, 420 |
41, 140 |
∴ So the LCM of the given numbers is 2 x 3 x 41 x 140 = 34440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/34440
Therefore, the GCF of Fractions 897/246,130/840 is 13/34440
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 246,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(246,840) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(246,840) x common factors =6 x 1 = 6
LCM(246,840) = ( 246 × 840 ) / 6
LCM(246,840) = 206640 / 6
LCM(246,840) = 34440
