∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 4
:1,2,4
Now, list down the factors of 45
:1,3,5,9,15,45
Now, list down the factors of 78
:1,2,3,6,13,26,39,78
Greatest Common Factor
We found the factors 4,45,78 . The biggest common factor number is the GCF number.
So the greatest common factor 4,45,78 is 1.
Lets's calculate LCM of 39,442,607
13 | 39, 442, 607 |
3, 34, 607 |
∴ So the LCM of the given numbers is 13 x 3 x 34 x 607 = 804882
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/804882
Therefore, the GCF of Fractions 4/39,45/442,78/607 is 1/804882
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 39,442,607 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,442,607) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(39,442,607) x common factors =1 x 13 = 13
LCM(39,442,607) = ( 39 × 442 × 607 ) / 13
LCM(39,442,607) = 10463466 / 13
LCM(39,442,607) = 804882
