Greatest Common Factor
We found the factors 38,40,968 . The biggest common factor number is the GCF number.
So the greatest common factor 38,40,968 is 2.
Lets's calculate LCM of 76,39,715
13 | 76, 39, 715 |
76, 3, 55 |
∴ So the LCM of the given numbers is 13 x 76 x 3 x 55 = 163020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/163020
Therefore, the GCF of Fractions 38/76,40/39,968/715 is 2/163020
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 76,39,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,39,715) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(76,39,715) x common factors =1 x 13 = 13
LCM(76,39,715) = ( 76 × 39 × 715 ) / 13
LCM(76,39,715) = 2119260 / 13
LCM(76,39,715) = 163020
