Greatest Common Factor
We found the factors 72,11,20,845 . The biggest common factor number is the GCF number.
So the greatest common factor 72,11,20,845 is 1.
Lets's calculate LCM of 60,95,99,98
2 | 60, 95, 99, 98 |
3 | 30, 95, 99, 49 |
5 | 10, 95, 33, 49 |
2, 19, 33, 49 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 2 x 19 x 33 x 49 = 1843380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1843380
Therefore, the GCF of Fractions 72/60,11/95,20/99,845/98 is 1/1843380
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 60,95,99,98 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,95,99,98) = 1
common factors(in case of two or more numbers have common factors) = 30
GCF(60,95,99,98) x common factors =1 x 30 = 30
LCM(60,95,99,98) = ( 60 × 95 × 99 × 98 ) / 30
LCM(60,95,99,98) = 55301400 / 30
LCM(60,95,99,98) = 1843380
