2 | 295, 886, 642 |
295, 443, 321 |
∴ So the LCM of the given numbers is 2 x 295 x 443 x 321 = 83899770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/83899770
Therefore, the GCF of Fractions 80/295,78/886,216/642 is 2/83899770
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 295,886,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(295,886,642) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(295,886,642) x common factors =1 x 2 = 2
LCM(295,886,642) = ( 295 × 886 × 642 ) / 2
LCM(295,886,642) = 167799540 / 2
LCM(295,886,642) = 83899770
