Lets's calculate LCM of 14,8750
2 | 14, 8750 |
7 | 7, 4375 |
1, 625 |
∴ So the LCM of the given numbers is 2 x 7 x 1 x 625 = 8750
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/8750
Therefore, the GCF of Fractions 378/14,558/8750 is 18/8750
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 14,8750 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,8750) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(14,8750) x common factors =14 x 1 = 14
LCM(14,8750) = ( 14 × 8750 ) / 14
LCM(14,8750) = 122500 / 14
LCM(14,8750) = 8750
