So the greatest common factor 769,209,140 is 1.
Lets's calculate LCM of 85,90,919
| 5 | 85, 90, 919 |
| 17, 18, 919 |
∴ So the LCM of the given numbers is 5 x 17 x 18 x 919 = 1406070
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1406070
Therefore, the GCF of Fractions 769/85,209/90,140/919 is 1/1406070
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 85,90,919 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,90,919) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(85,90,919) x common factors =1 x 5 = 5
LCM(85,90,919) = ( 85 × 90 × 919 ) / 5
LCM(85,90,919) = 7030350 / 5
LCM(85,90,919) = 1406070
