So the greatest common factor 51,781,862 is 1.
Lets's calculate LCM of 91,79,871
13 | 91, 79, 871 |
7, 79, 67 |
∴ So the LCM of the given numbers is 13 x 7 x 79 x 67 = 481663
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/481663
Therefore, the GCF of Fractions 51/91,781/79,862/871 is 1/481663
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 91,79,871 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,79,871) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(91,79,871) x common factors =1 x 13 = 13
LCM(91,79,871) = ( 91 × 79 × 871 ) / 13
LCM(91,79,871) = 6261619 / 13
LCM(91,79,871) = 481663
