1,3,929,2787
Greatest Common Factor
We found the factors 31,2787 . The biggest common factor number is the GCF number.
So the greatest common factor 31,2787 is 1.
Lets's calculate LCM of 840,5492
2 | 840, 5492 |
2 | 420, 2746 |
210, 1373 |
∴ So the LCM of the given numbers is 2 x 2 x 210 x 1373 = 1153320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1153320
Therefore, the GCF of Fractions 31/840,2787/5492 is 1/1153320
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 840,5492 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,5492) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(840,5492) x common factors =4 x 1 = 4
LCM(840,5492) = ( 840 × 5492 ) / 4
LCM(840,5492) = 4613280 / 4
LCM(840,5492) = 1153320
