Lets's calculate LCM of 753,544,644
2 | 753, 544, 644 |
2 | 753, 272, 322 |
753, 136, 161 |
∴ So the LCM of the given numbers is 2 x 2 x 753 x 136 x 161 = 65950752
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/65950752
Therefore, the GCF of Fractions 12/753,744/544,820/644 is 4/65950752
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 753,544,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(753,544,644) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(753,544,644) x common factors =1 x 4 = 4
LCM(753,544,644) = ( 753 × 544 × 644 ) / 4
LCM(753,544,644) = 263803008 / 4
LCM(753,544,644) = 65950752
