So the greatest common factor 68,698,829 is 1.
Lets's calculate LCM of 31,39,650
13 | 31, 39, 650 |
31, 3, 50 |
∴ So the LCM of the given numbers is 13 x 31 x 3 x 50 = 60450
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/60450
Therefore, the GCF of Fractions 68/31,698/39,829/650 is 1/60450
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 31,39,650 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,39,650) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(31,39,650) x common factors =1 x 13 = 13
LCM(31,39,650) = ( 31 × 39 × 650 ) / 13
LCM(31,39,650) = 785850 / 13
LCM(31,39,650) = 60450
