So the greatest common factor 75,486,217 is 1.
Lets's calculate LCM of 931,779,917
7 | 931, 779, 917 |
19 | 133, 779, 131 |
7, 41, 131 |
∴ So the LCM of the given numbers is 7 x 19 x 7 x 41 x 131 = 5000401
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5000401
Therefore, the GCF of Fractions 75/931,486/779,217/917 is 1/5000401
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 931,779,917 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(931,779,917) = 1
common factors(in case of two or more numbers have common factors) = 133
GCF(931,779,917) x common factors =1 x 133 = 133
LCM(931,779,917) = ( 931 × 779 × 917 ) / 133
LCM(931,779,917) = 665053333 / 133
LCM(931,779,917) = 5000401
