Lets's calculate GCF of 77,47
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 890,4468
2 | 890, 4468 |
445, 2234 |
∴ So the LCM of the given numbers is 2 x 445 x 2234 = 1988260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1988260
Therefore, the GCF of Fractions 77/890,47/4468 is 1/1988260
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 890,4468 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(890,4468) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(890,4468) x common factors =2 x 1 = 2
LCM(890,4468) = ( 890 × 4468 ) / 2
LCM(890,4468) = 3976520 / 2
LCM(890,4468) = 1988260
