So the greatest common factor 791,664 is 1.
Lets's calculate LCM of 130,694
2 | 130, 694 |
65, 347 |
∴ So the LCM of the given numbers is 2 x 65 x 347 = 45110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/45110
Therefore, the GCF of Fractions 791/130,664/694 is 1/45110
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 130,694 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(130,694) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(130,694) x common factors =2 x 1 = 2
LCM(130,694) = ( 130 × 694 ) / 2
LCM(130,694) = 90220 / 2
LCM(130,694) = 45110
