So the greatest common factor 7920,1876 is 4.
Lets's calculate LCM of 490,7645
5 | 490, 7645 |
98, 1529 |
∴ So the LCM of the given numbers is 5 x 98 x 1529 = 749210
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/749210
Therefore, the GCF of Fractions 7920/490,1876/7645 is 4/749210
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 490,7645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,7645) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(490,7645) x common factors =5 x 1 = 5
LCM(490,7645) = ( 490 × 7645 ) / 5
LCM(490,7645) = 3746050 / 5
LCM(490,7645) = 749210
