Greatest Common Factor
We found the factors 26,972,551 . The biggest common factor number is the GCF number.
So the greatest common factor 26,972,551 is 1.
Lets's calculate LCM of 30,21,980
2 | 30, 21, 980 |
3 | 15, 21, 490 |
5 | 5, 7, 490 |
7 | 1, 7, 98 |
1, 1, 14 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 1 x 1 x 14 = 2940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2940
Therefore, the GCF of Fractions 26/30,972/21,551/980 is 1/2940
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 30,21,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,21,980) = 1
common factors(in case of two or more numbers have common factors) = 210
GCF(30,21,980) x common factors =1 x 210 = 210
LCM(30,21,980) = ( 30 × 21 × 980 ) / 210
LCM(30,21,980) = 617400 / 210
LCM(30,21,980) = 2940
