Greatest Common Factor
We found the factors 992,7215 . The biggest common factor number is the GCF number.
So the greatest common factor 992,7215 is 1.
Lets's calculate LCM of 274,830
2 | 274, 830 |
137, 415 |
∴ So the LCM of the given numbers is 2 x 137 x 415 = 113710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/113710
Therefore, the GCF of Fractions 992/274,7215/830 is 1/113710
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 274,830 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(274,830) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(274,830) x common factors =2 x 1 = 2
LCM(274,830) = ( 274 × 830 ) / 2
LCM(274,830) = 227420 / 2
LCM(274,830) = 113710
