Lets's calculate LCM of 782,5720
2 | 782, 5720 |
391, 2860 |
∴ So the LCM of the given numbers is 2 x 391 x 2860 = 2236520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/2236520
Therefore, the GCF of Fractions 7144/782,8828/5720 is 4/2236520
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 782,5720 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(782,5720) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(782,5720) x common factors =2 x 1 = 2
LCM(782,5720) = ( 782 × 5720 ) / 2
LCM(782,5720) = 4473040 / 2
LCM(782,5720) = 2236520
