So the greatest common factor 442,640 is 2.
Lets's calculate LCM of 40,776
2 | 40, 776 |
2 | 20, 388 |
2 | 10, 194 |
5, 97 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 97 = 3880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3880
Therefore, the GCF of Fractions 442/40,640/776 is 2/3880
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 40,776 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,776) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(40,776) x common factors =8 x 1 = 8
LCM(40,776) = ( 40 × 776 ) / 8
LCM(40,776) = 31040 / 8
LCM(40,776) = 3880
