Lets's calculate LCM of 435,515
5 | 435, 515 |
87, 103 |
∴ So the LCM of the given numbers is 5 x 87 x 103 = 44805
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/44805
Therefore, the GCF of Fractions 781/435,2442/515 is 11/44805
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 435,515 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(435,515) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(435,515) x common factors =5 x 1 = 5
LCM(435,515) = ( 435 × 515 ) / 5
LCM(435,515) = 224025 / 5
LCM(435,515) = 44805
