So the greatest common factor 270,9090 is 90.
Lets's calculate LCM of 696,770
2 | 696, 770 |
348, 385 |
∴ So the LCM of the given numbers is 2 x 348 x 385 = 267960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 90/267960
Therefore, the GCF of Fractions 270/696,9090/770 is 90/267960
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 696,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(696,770) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(696,770) x common factors =2 x 1 = 2
LCM(696,770) = ( 696 × 770 ) / 2
LCM(696,770) = 535920 / 2
LCM(696,770) = 267960
