Greatest Common Factor
We found the factors 95,94,18,18 . The biggest common factor number is the GCF number.
So the greatest common factor 95,94,18,18 is 1.
Lets's calculate LCM of 39,77,30,78
2 | 39, 77, 30, 78 |
3 | 39, 77, 15, 39 |
13 | 13, 77, 5, 13 |
1, 77, 5, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 77 x 5 x 1 = 30030
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30030
Therefore, the GCF of Fractions 95/39,94/77,18/30,18/78 is 1/30030
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 39,77,30,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,77,30,78) = 1
common factors(in case of two or more numbers have common factors) = 234
GCF(39,77,30,78) x common factors =1 x 234 = 234
LCM(39,77,30,78) = ( 39 × 77 × 30 × 78 ) / 234
LCM(39,77,30,78) = 7027020 / 234
LCM(39,77,30,78) = 30030
