So the greatest common factor 872,370 is 2.
Lets's calculate LCM of 690,824
2 | 690, 824 |
345, 412 |
∴ So the LCM of the given numbers is 2 x 345 x 412 = 284280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/284280
Therefore, the GCF of Fractions 872/690,370/824 is 2/284280
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 690,824 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(690,824) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(690,824) x common factors =2 x 1 = 2
LCM(690,824) = ( 690 × 824 ) / 2
LCM(690,824) = 568560 / 2
LCM(690,824) = 284280
