Greatest Common Factor
We found the factors 77,37,55,19 . The biggest common factor number is the GCF number.
So the greatest common factor 77,37,55,19 is 1.
Lets's calculate LCM of 50,68,75,945
2 | 50, 68, 75, 945 |
3 | 25, 34, 75, 945 |
5 | 25, 34, 25, 315 |
5 | 5, 34, 5, 63 |
1, 34, 1, 63 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 5 x 1 x 34 x 1 x 63 = 321300
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/321300
Therefore, the GCF of Fractions 77/50,37/68,55/75,19/945 is 1/321300
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 50,68,75,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(50,68,75,945) = 1
common factors(in case of two or more numbers have common factors) = 750
GCF(50,68,75,945) x common factors =1 x 750 = 750
LCM(50,68,75,945) = ( 50 × 68 × 75 × 945 ) / 750
LCM(50,68,75,945) = 240975000 / 750
LCM(50,68,75,945) = 321300
