Lets's calculate LCM of 202,898
2 | 202, 898 |
101, 449 |
∴ So the LCM of the given numbers is 2 x 101 x 449 = 90698
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 38/90698
Therefore, the GCF of Fractions 988/202,646/898 is 38/90698
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 202,898 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(202,898) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(202,898) x common factors =2 x 1 = 2
LCM(202,898) = ( 202 × 898 ) / 2
LCM(202,898) = 181396 / 2
LCM(202,898) = 90698
