Lets's calculate GCF of 40,76
2 | 40, 76 |
2 | 20, 38 |
10, 19 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Now, list down the factors of 40
:1,2,4,5,8,10,20,40
Now, list down the factors of 76
:1,2,4,19,38,76
Greatest Common Factor
We found the factors 40,76 . The biggest common factor number is the GCF number.
So the greatest common factor 40,76 is 4.
Lets's calculate LCM of 705,4915
5 | 705, 4915 |
141, 983 |
∴ So the LCM of the given numbers is 5 x 141 x 983 = 693015
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/693015
Therefore, the GCF of Fractions 40/705,76/4915 is 4/693015
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 705,4915 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(705,4915) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(705,4915) x common factors =5 x 1 = 5
LCM(705,4915) = ( 705 × 4915 ) / 5
LCM(705,4915) = 3465075 / 5
LCM(705,4915) = 693015
