So the greatest common factor 72,867,742 is 1.
Lets's calculate LCM of 19,88,913
11 | 19, 88, 913 |
19, 8, 83 |
∴ So the LCM of the given numbers is 11 x 19 x 8 x 83 = 138776
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/138776
Therefore, the GCF of Fractions 72/19,867/88,742/913 is 1/138776
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 19,88,913 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,88,913) = 1
common factors(in case of two or more numbers have common factors) = 11
GCF(19,88,913) x common factors =1 x 11 = 11
LCM(19,88,913) = ( 19 × 88 × 913 ) / 11
LCM(19,88,913) = 1526536 / 11
LCM(19,88,913) = 138776
