Given numbers are 334,840,246,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 334,840,246,690 is 132284040.
Find LCM of 334,840,246,690 with Prime Factorization
| 2 | 334, 840, 246, 690 |
| 3 | 167, 420, 123, 345 |
| 5 | 167, 140, 41, 115 |
| 167, 28, 41, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 167 x 28 x 41 x 23 = 132284040
Therefore, the lowest common multiple of 334,840,246,690 is 132284040.
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.
334 x 840 x 246 x 690 = 47622254400
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.
334 : 1, 2, 167, 334
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
246 : 1, 2, 3, 6, 41, 82, 123, 246
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 334,840,246,690, is 2.
Now, the common factors can be found like this.
334:2x 167
840:2x 2x 2x 3x 5x 7
246:2x 3x 41
690:2x 3x 5x 23
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 5 = 180
Therefore, the value for common factors is 180.
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 = 47622254400/(2x180)
LCM = 47622254400/360
LCM = 132284040
Thus, we can understand that the LCM of 334,840,246,690 is 132284040.
