Lets's calculate LCM of 196,214,423
2 | 196, 214, 423 |
98, 107, 423 |
∴ So the LCM of the given numbers is 2 x 98 x 107 x 423 = 8871156
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8871156
Therefore, the GCF of Fractions 857/196,555/214,621/423 is 1/8871156
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 196,214,423 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(196,214,423) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(196,214,423) x common factors =1 x 2 = 2
LCM(196,214,423) = ( 196 × 214 × 423 ) / 2
LCM(196,214,423) = 17742312 / 2
LCM(196,214,423) = 8871156
