Given numbers are 294,861,783,840,386
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 294,861,783,840,386 is 12143922840.
Find LCM of 294,861,783,840,386 with Prime Factorization
| 2 | 294, 861, 783, 840, 386 |
| 3 | 147, 861, 783, 420, 193 |
| 7 | 49, 287, 261, 140, 193 |
| 7, 41, 261, 20, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 41 x 261 x 20 x 193 = 12143922840
Therefore, the lowest common multiple of 294,861,783,840,386 is 12143922840.
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.
294 x 861 x 783 x 840 x 386 = 64265639669280
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.
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
861 : 1, 3, 7, 21, 41, 123, 287, 861
783 : 1, 3, 9, 27, 29, 87, 261, 783
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
386 : 1, 2, 193, 386
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 294,861,783,840,386, is 1.
Now, the common factors can be found like this.
294:2x 3x 7x 7
861:3x 7x 41
783:3x 3x 3x 29
840:2x 2x 2x 3x 5x 7
386:2x 193
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 3x 3x 7x 7 = 5292
Therefore, the value for common factors is 5292.
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 = 64265639669280/(1x5292)
LCM = 64265639669280/5292
LCM = 12143922840
Thus, we can understand that the LCM of 294,861,783,840,386 is 12143922840.
