Greatest Common Factor
We found the factors 42,910,760 . The biggest common factor number is the GCF number.
So the greatest common factor 42,910,760 is 2.
Lets's calculate LCM of 91,78,145
13 | 91, 78, 145 |
7, 6, 145 |
∴ So the LCM of the given numbers is 13 x 7 x 6 x 145 = 79170
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/79170
Therefore, the GCF of Fractions 42/91,910/78,760/145 is 2/79170
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 91,78,145 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,78,145) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(91,78,145) x common factors =1 x 13 = 13
LCM(91,78,145) = ( 91 × 78 × 145 ) / 13
LCM(91,78,145) = 1029210 / 13
LCM(91,78,145) = 79170
