Greatest Common Factor
We found the factors 65,64,720 . The biggest common factor number is the GCF number.
So the greatest common factor 65,64,720 is 1.
Lets's calculate LCM of 920,840,808
2 | 920, 840, 808 |
2 | 460, 420, 404 |
2 | 230, 210, 202 |
5 | 115, 105, 101 |
23, 21, 101 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 23 x 21 x 101 = 1951320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1951320
Therefore, the GCF of Fractions 65/920,64/840,720/808 is 1/1951320
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 920,840,808 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(920,840,808) = 8
common factors(in case of two or more numbers have common factors) = 40
GCF(920,840,808) x common factors =8 x 40 = 320
LCM(920,840,808) = ( 920 × 840 × 808 ) / 320
LCM(920,840,808) = 624422400 / 320
LCM(920,840,808) = 1951320
