So the greatest common factor 931,920 is 1.
Lets's calculate LCM of 765,485
5 | 765, 485 |
153, 97 |
∴ So the LCM of the given numbers is 5 x 153 x 97 = 74205
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/74205
Therefore, the GCF of Fractions 931/765,920/485 is 1/74205
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 765,485 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(765,485) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(765,485) x common factors =5 x 1 = 5
LCM(765,485) = ( 765 × 485 ) / 5
LCM(765,485) = 371025 / 5
LCM(765,485) = 74205
