Lets's calculate LCM of 728,2802
2 | 728, 2802 |
364, 1401 |
∴ So the LCM of the given numbers is 2 x 364 x 1401 = 1019928
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1019928
Therefore, the GCF of Fractions 1245/728,3807/2802 is 3/1019928
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 728,2802 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(728,2802) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(728,2802) x common factors =2 x 1 = 2
LCM(728,2802) = ( 728 × 2802 ) / 2
LCM(728,2802) = 2039856 / 2
LCM(728,2802) = 1019928
