Greatest Common Factor
We found the factors 1902,6467 . The biggest common factor number is the GCF number.
So the greatest common factor 1902,6467 is 1.
Lets's calculate LCM of 640,1948
2 | 640, 1948 |
2 | 320, 974 |
160, 487 |
∴ So the LCM of the given numbers is 2 x 2 x 160 x 487 = 311680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/311680
Therefore, the GCF of Fractions 1902/640,6467/1948 is 1/311680
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 640,1948 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,1948) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(640,1948) x common factors =4 x 1 = 4
LCM(640,1948) = ( 640 × 1948 ) / 4
LCM(640,1948) = 1246720 / 4
LCM(640,1948) = 311680
