Factors of 178
List of positive integer factors of 178 that divides 178 without a remainder.
1,2,89,178
Greatest Common Factor
We found the factors 734,178 . The biggest common factor number is the GCF number.
So the greatest common factor 734,178 is 2.
Lets's calculate LCM of 78,3840
2 | 78, 3840 |
3 | 39, 1920 |
13, 640 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 640 = 49920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/49920
Therefore, the GCF of Fractions 734/78,178/3840 is 2/49920
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 78,3840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,3840) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(78,3840) x common factors =6 x 1 = 6
LCM(78,3840) = ( 78 × 3840 ) / 6
LCM(78,3840) = 299520 / 6
LCM(78,3840) = 49920
