Lets's calculate LCM of 502,7678
2 | 502, 7678 |
251, 3839 |
∴ So the LCM of the given numbers is 2 x 251 x 3839 = 1927178
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1927178
Therefore, the GCF of Fractions 1278/502,1961/7678 is 1/1927178
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 502,7678 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(502,7678) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(502,7678) x common factors =2 x 1 = 2
LCM(502,7678) = ( 502 × 7678 ) / 2
LCM(502,7678) = 3854356 / 2
LCM(502,7678) = 1927178
