So the greatest common factor 689,651,182 is 1.
Lets's calculate LCM of 532,260,786
2 | 532, 260, 786 |
2 | 266, 130, 393 |
133, 65, 393 |
∴ So the LCM of the given numbers is 2 x 2 x 133 x 65 x 393 = 13589940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13589940
Therefore, the GCF of Fractions 689/532,651/260,182/786 is 1/13589940
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 532,260,786 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(532,260,786) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(532,260,786) x common factors =2 x 4 = 8
LCM(532,260,786) = ( 532 × 260 × 786 ) / 8
LCM(532,260,786) = 108719520 / 8
LCM(532,260,786) = 13589940
