Greatest Common Factor
We found the factors 49,60,68,86 . The biggest common factor number is the GCF number.
So the greatest common factor 49,60,68,86 is 1.
Lets's calculate LCM of 24,67,98,78
2 | 24, 67, 98, 78 |
3 | 12, 67, 49, 39 |
4, 67, 49, 13 |
∴ So the LCM of the given numbers is 2 x 3 x 4 x 67 x 49 x 13 = 1024296
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1024296
Therefore, the GCF of Fractions 49/24,60/67,68/98,86/78 is 1/1024296
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 24,67,98,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,67,98,78) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(24,67,98,78) x common factors =1 x 12 = 12
LCM(24,67,98,78) = ( 24 × 67 × 98 × 78 ) / 12
LCM(24,67,98,78) = 12291552 / 12
LCM(24,67,98,78) = 1024296
