Greatest Common Factor
We found the factors 6420,8869 . The biggest common factor number is the GCF number.
So the greatest common factor 6420,8869 is 1.
Lets's calculate LCM of 65,890
| 5 | 65, 890 |
| 13, 178 |
∴ So the LCM of the given numbers is 5 x 13 x 178 = 11570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11570
Therefore, the GCF of Fractions 6420/65,8869/890 is 1/11570
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 65,890 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,890) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(65,890) x common factors =5 x 1 = 5
LCM(65,890) = ( 65 × 890 ) / 5
LCM(65,890) = 57850 / 5
LCM(65,890) = 11570
