Greatest Common Factor
We found the factors 23,11,985 . The biggest common factor number is the GCF number.
So the greatest common factor 23,11,985 is 1.
Lets's calculate LCM of 214,708,421
2 | 214, 708, 421 |
107, 354, 421 |
∴ So the LCM of the given numbers is 2 x 107 x 354 x 421 = 31893276
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/31893276
Therefore, the GCF of Fractions 23/214,11/708,985/421 is 1/31893276
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 214,708,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(214,708,421) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(214,708,421) x common factors =1 x 2 = 2
LCM(214,708,421) = ( 214 × 708 × 421 ) / 2
LCM(214,708,421) = 63786552 / 2
LCM(214,708,421) = 31893276
