:1,2,4,5,8,10,16,20,25,40,50,80,100,200,400
Greatest Common Factor
We found the factors 124,400 . The biggest common factor number is the GCF number.
So the greatest common factor 124,400 is 4.
Lets's calculate LCM of 308,486
2 | 308, 486 |
154, 243 |
∴ So the LCM of the given numbers is 2 x 154 x 243 = 74844
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/74844
Therefore, the GCF of Fractions 124/308,400/486 is 4/74844
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 308,486 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(308,486) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(308,486) x common factors =2 x 1 = 2
LCM(308,486) = ( 308 × 486 ) / 2
LCM(308,486) = 149688 / 2
LCM(308,486) = 74844
