So the greatest common factor 980,798 is 14.
Lets's calculate LCM of 655,740
5 | 655, 740 |
131, 148 |
∴ So the LCM of the given numbers is 5 x 131 x 148 = 96940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/96940
Therefore, the GCF of Fractions 980/655,798/740 is 14/96940
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 655,740 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(655,740) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(655,740) x common factors =5 x 1 = 5
LCM(655,740) = ( 655 × 740 ) / 5
LCM(655,740) = 484700 / 5
LCM(655,740) = 96940
