Lets's calculate LCM of 497,639
71 | 497, 639 |
7, 9 |
∴ So the LCM of the given numbers is 71 x 7 x 9 = 4473
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4473
Therefore, the GCF of Fractions 871/497,760/639 is 1/4473
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 497,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(497,639) = 71
common factors(in case of two or more numbers have common factors) = 1
GCF(497,639) x common factors =71 x 1 = 71
LCM(497,639) = ( 497 × 639 ) / 71
LCM(497,639) = 317583 / 71
LCM(497,639) = 4473
