Lets's calculate LCM of 690,4520
2 | 690, 4520 |
5 | 345, 2260 |
69, 452 |
∴ So the LCM of the given numbers is 2 x 5 x 69 x 452 = 311880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/311880
Therefore, the GCF of Fractions 618/690,1204/4520 is 2/311880
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 690,4520 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(690,4520) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(690,4520) x common factors =10 x 1 = 10
LCM(690,4520) = ( 690 × 4520 ) / 10
LCM(690,4520) = 3118800 / 10
LCM(690,4520) = 311880
