Greatest Common Factor
We found the factors 76,74,20,40 . The biggest common factor number is the GCF number.
So the greatest common factor 76,74,20,40 is 2.
Lets's calculate LCM of 98,98,24,34
2 | 98, 98, 24, 34 |
7 | 49, 49, 12, 17 |
7 | 7, 7, 12, 17 |
1, 1, 12, 17 |
∴ So the LCM of the given numbers is 2 x 7 x 7 x 1 x 1 x 12 x 17 = 19992
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/19992
Therefore, the GCF of Fractions 76/98,74/98,20/24,40/34 is 2/19992
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 98,98,24,34 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(98,98,24,34) = 2
common factors(in case of two or more numbers have common factors) = 196
GCF(98,98,24,34) x common factors =2 x 196 = 392
LCM(98,98,24,34) = ( 98 × 98 × 24 × 34 ) / 392
LCM(98,98,24,34) = 7836864 / 392
LCM(98,98,24,34) = 19992
