Find LCM of 828,781,760,447,893 with Prime Factorization
| 2 | 828, 781, 760, 447, 893 |
| 2 | 414, 781, 380, 447, 893 |
| 3 | 207, 781, 190, 447, 893 |
| 19 | 69, 781, 190, 149, 893 |
| 69, 781, 10, 149, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 69 x 781 x 10 x 149 x 47 = 860437040760
Therefore, the lowest common multiple of 828,781,760,447,893 is 860437040760.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
828 x 781 x 760 x 447 x 893 = 196179645293280
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
781 : 1, 11, 71, 781
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
447 : 1, 3, 149, 447
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,781,760,447,893, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
781:11x 71
760:2x 2x 2x 5x 19
447:3x 149
893:19x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 19 = 228
Therefore, the value for common factors is 228.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 196179645293280/(1x228)
LCM = 196179645293280/228
LCM = 860437040760
Thus, we can understand that the LCM of 828,781,760,447,893 is 860437040760.
