:1,2,5,7,10,11,14,22,35,55,70,77,110,154,385,770
Greatest Common Factor
We found the factors 140,770 . The biggest common factor number is the GCF number.
So the greatest common factor 140,770 is 70.
Lets's calculate LCM of 68,2834
2 | 68, 2834 |
34, 1417 |
∴ So the LCM of the given numbers is 2 x 34 x 1417 = 96356
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 70/96356
Therefore, the GCF of Fractions 140/68,770/2834 is 70/96356
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 68,2834 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,2834) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(68,2834) x common factors =2 x 1 = 2
LCM(68,2834) = ( 68 × 2834 ) / 2
LCM(68,2834) = 192712 / 2
LCM(68,2834) = 96356
