Lets's calculate LCM of 898,370
2 | 898, 370 |
449, 185 |
∴ So the LCM of the given numbers is 2 x 449 x 185 = 166130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/166130
Therefore, the GCF of Fractions 897/898,455/370 is 13/166130
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 898,370 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(898,370) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(898,370) x common factors =2 x 1 = 2
LCM(898,370) = ( 898 × 370 ) / 2
LCM(898,370) = 332260 / 2
LCM(898,370) = 166130
