Greatest Common Factor
We found the factors 639,7515 . The biggest common factor number is the GCF number.
So the greatest common factor 639,7515 is 9.
Lets's calculate LCM of 14,492
2 | 14, 492 |
7, 246 |
∴ So the LCM of the given numbers is 2 x 7 x 246 = 3444
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/3444
Therefore, the GCF of Fractions 639/14,7515/492 is 9/3444
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 14,492 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,492) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(14,492) x common factors =2 x 1 = 2
LCM(14,492) = ( 14 × 492 ) / 2
LCM(14,492) = 6888 / 2
LCM(14,492) = 3444
