So the greatest common factor 4230,2190 is 30.
Lets's calculate LCM of 670,392
2 | 670, 392 |
335, 196 |
∴ So the LCM of the given numbers is 2 x 335 x 196 = 131320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/131320
Therefore, the GCF of Fractions 4230/670,2190/392 is 30/131320
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 670,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(670,392) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(670,392) x common factors =2 x 1 = 2
LCM(670,392) = ( 670 × 392 ) / 2
LCM(670,392) = 262640 / 2
LCM(670,392) = 131320
