So the greatest common factor 473,420 is 1.
Lets's calculate LCM of 702,890
2 | 702, 890 |
351, 445 |
∴ So the LCM of the given numbers is 2 x 351 x 445 = 312390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/312390
Therefore, the GCF of Fractions 473/702,420/890 is 1/312390
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 702,890 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(702,890) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(702,890) x common factors =2 x 1 = 2
LCM(702,890) = ( 702 × 890 ) / 2
LCM(702,890) = 624780 / 2
LCM(702,890) = 312390
