Greatest Common Factor
We found the factors 8,16,84,379 . The biggest common factor number is the GCF number.
So the greatest common factor 8,16,84,379 is 1.
Lets's calculate LCM of 91,58,546,862
2 | 91, 58, 546, 862 |
7 | 91, 29, 273, 431 |
13 | 13, 29, 39, 431 |
1, 29, 3, 431 |
∴ So the LCM of the given numbers is 2 x 7 x 13 x 1 x 29 x 3 x 431 = 6824454
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6824454
Therefore, the GCF of Fractions 8/91,16/58,84/546,379/862 is 1/6824454
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 91,58,546,862 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,58,546,862) = 1
common factors(in case of two or more numbers have common factors) = 364
GCF(91,58,546,862) x common factors =1 x 364 = 364
LCM(91,58,546,862) = ( 91 × 58 × 546 × 862 ) / 364
LCM(91,58,546,862) = 2484101256 / 364
LCM(91,58,546,862) = 6824454
