2 | 638, 4222 |
319, 2111 |
∴ So the LCM of the given numbers is 2 x 319 x 2111 = 1346818
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1346818
Therefore, the GCF of Fractions 4385/638,2808/4222 is 1/1346818
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 638,4222 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(638,4222) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(638,4222) x common factors =2 x 1 = 2
LCM(638,4222) = ( 638 × 4222 ) / 2
LCM(638,4222) = 2693636 / 2
LCM(638,4222) = 1346818
