So the greatest common factor 69,38,219 is 1.
Lets's calculate LCM of 680,808,360
2 | 680, 808, 360 |
2 | 340, 404, 180 |
2 | 170, 202, 90 |
5 | 85, 101, 45 |
17, 101, 9 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 17 x 101 x 9 = 618120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/618120
Therefore, the GCF of Fractions 69/680,38/808,219/360 is 1/618120
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 680,808,360 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(680,808,360) = 8
common factors(in case of two or more numbers have common factors) = 40
GCF(680,808,360) x common factors =8 x 40 = 320
LCM(680,808,360) = ( 680 × 808 × 360 ) / 320
LCM(680,808,360) = 197798400 / 320
LCM(680,808,360) = 618120
