Lets's calculate LCM of 438,9020
2 | 438, 9020 |
219, 4510 |
∴ So the LCM of the given numbers is 2 x 219 x 4510 = 1975380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1975380
Therefore, the GCF of Fractions 1238/438,1243/9020 is 1/1975380
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 438,9020 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(438,9020) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(438,9020) x common factors =2 x 1 = 2
LCM(438,9020) = ( 438 × 9020 ) / 2
LCM(438,9020) = 3950760 / 2
LCM(438,9020) = 1975380
