So the greatest common factor 874,420 is 2.
Lets's calculate LCM of 562,784
2 | 562, 784 |
281, 392 |
∴ So the LCM of the given numbers is 2 x 281 x 392 = 220304
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/220304
Therefore, the GCF of Fractions 874/562,420/784 is 2/220304
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 562,784 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(562,784) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(562,784) x common factors =2 x 1 = 2
LCM(562,784) = ( 562 × 784 ) / 2
LCM(562,784) = 440608 / 2
LCM(562,784) = 220304
