So the greatest common factor 25,490,115 is 5.
Lets's calculate LCM of 824,412,889
2 | 824, 412, 889 |
2 | 412, 206, 889 |
103 | 103, 206, 889 |
1, 2, 889 |
∴ So the LCM of the given numbers is 2 x 2 x 103 x 1 x 2 x 889 = 732536
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/732536
Therefore, the GCF of Fractions 25/824,490/412,115/889 is 5/732536
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 824,412,889 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(824,412,889) = 1
common factors(in case of two or more numbers have common factors) = 412
GCF(824,412,889) x common factors =1 x 412 = 412
LCM(824,412,889) = ( 824 × 412 × 889 ) / 412
LCM(824,412,889) = 301804832 / 412
LCM(824,412,889) = 732536
