Lets's calculate LCM of 520,344
2 | 520, 344 |
2 | 260, 172 |
2 | 130, 86 |
65, 43 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 65 x 43 = 22360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/22360
Therefore, the GCF of Fractions 781/520,7198/344 is 1/22360
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 520,344 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,344) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(520,344) x common factors =8 x 1 = 8
LCM(520,344) = ( 520 × 344 ) / 8
LCM(520,344) = 178880 / 8
LCM(520,344) = 22360
