Greatest Common Factor
We found the factors 924,972 . The biggest common factor number is the GCF number.
So the greatest common factor 924,972 is 12.
Lets's calculate LCM of 214,486
2 | 214, 486 |
107, 243 |
∴ So the LCM of the given numbers is 2 x 107 x 243 = 52002
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/52002
Therefore, the GCF of Fractions 924/214,972/486 is 12/52002
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 214,486 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(214,486) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(214,486) x common factors =2 x 1 = 2
LCM(214,486) = ( 214 × 486 ) / 2
LCM(214,486) = 104004 / 2
LCM(214,486) = 52002
