Greatest Common Factor
We found the factors 10,50,85,47 . The biggest common factor number is the GCF number.
So the greatest common factor 10,50,85,47 is 1.
Lets's calculate LCM of 90,87,53,66
2 | 90, 87, 53, 66 |
3 | 45, 87, 53, 33 |
15, 29, 53, 11 |
∴ So the LCM of the given numbers is 2 x 3 x 15 x 29 x 53 x 11 = 1521630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1521630
Therefore, the GCF of Fractions 10/90,50/87,85/53,47/66 is 1/1521630
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 90,87,53,66 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,87,53,66) = 1
common factors(in case of two or more numbers have common factors) = 18
GCF(90,87,53,66) x common factors =1 x 18 = 18
LCM(90,87,53,66) = ( 90 × 87 × 53 × 66 ) / 18
LCM(90,87,53,66) = 27389340 / 18
LCM(90,87,53,66) = 1521630
