Greatest Common Factor
We found the factors 10,86,78,12 . The biggest common factor number is the GCF number.
So the greatest common factor 10,86,78,12 is 2.
Lets's calculate LCM of 67,18,78,54
2 | 67, 18, 78, 54 |
3 | 67, 9, 39, 27 |
3 | 67, 3, 13, 9 |
67, 1, 13, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 67 x 1 x 13 x 3 = 47034
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/47034
Therefore, the GCF of Fractions 10/67,86/18,78/78,12/54 is 2/47034
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 67,18,78,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,18,78,54) = 1
common factors(in case of two or more numbers have common factors) = 108
GCF(67,18,78,54) x common factors =1 x 108 = 108
LCM(67,18,78,54) = ( 67 × 18 × 78 × 54 ) / 108
LCM(67,18,78,54) = 5079672 / 108
LCM(67,18,78,54) = 47034
