Greatest Common Factor
We found the factors 25,69,16,82 . The biggest common factor number is the GCF number.
So the greatest common factor 25,69,16,82 is 1.
Lets's calculate LCM of 94,52,78,90
2 | 94, 52, 78, 90 |
3 | 47, 26, 39, 45 |
13 | 47, 26, 13, 15 |
47, 2, 1, 15 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 47 x 2 x 1 x 15 = 109980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/109980
Therefore, the GCF of Fractions 25/94,69/52,16/78,82/90 is 1/109980
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 94,52,78,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(94,52,78,90) = 2
common factors(in case of two or more numbers have common factors) = 156
GCF(94,52,78,90) x common factors =2 x 156 = 312
LCM(94,52,78,90) = ( 94 × 52 × 78 × 90 ) / 312
LCM(94,52,78,90) = 34313760 / 312
LCM(94,52,78,90) = 109980
