Greatest Common Factor
We found the factors 797,842,895 . The biggest common factor number is the GCF number.
So the greatest common factor 797,842,895 is 1.
Lets's calculate LCM of 86,70,91
2 | 86, 70, 91 |
7 | 43, 35, 91 |
43, 5, 13 |
∴ So the LCM of the given numbers is 2 x 7 x 43 x 5 x 13 = 39130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/39130
Therefore, the GCF of Fractions 797/86,842/70,895/91 is 1/39130
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 86,70,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,70,91) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(86,70,91) x common factors =1 x 14 = 14
LCM(86,70,91) = ( 86 × 70 × 91 ) / 14
LCM(86,70,91) = 547820 / 14
LCM(86,70,91) = 39130
