So the greatest common factor 662,972 is 2.
Lets's calculate LCM of 482,644
2 | 482, 644 |
241, 322 |
∴ So the LCM of the given numbers is 2 x 241 x 322 = 155204
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/155204
Therefore, the GCF of Fractions 662/482,972/644 is 2/155204
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 482,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(482,644) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(482,644) x common factors =2 x 1 = 2
LCM(482,644) = ( 482 × 644 ) / 2
LCM(482,644) = 310408 / 2
LCM(482,644) = 155204
