So the greatest common factor 7,10,86,784 is 1.
Lets's calculate LCM of 86,26,857,982
2 | 86, 26, 857, 982 |
43, 13, 857, 491 |
∴ So the LCM of the given numbers is 2 x 43 x 13 x 857 x 491 = 470439866
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/470439866
Therefore, the GCF of Fractions 7/86,10/26,86/857,784/982 is 1/470439866
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 86,26,857,982 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,26,857,982) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(86,26,857,982) x common factors =1 x 4 = 4
LCM(86,26,857,982) = ( 86 × 26 × 857 × 982 ) / 4
LCM(86,26,857,982) = 1881759464 / 4
LCM(86,26,857,982) = 470439866
