Given numbers are 354,396,240,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 354,396,240,494 is 115418160.
Find LCM of 354,396,240,494 with Prime Factorization
| 2 | 354, 396, 240, 494 |
| 2 | 177, 198, 120, 247 |
| 3 | 177, 99, 60, 247 |
| 59, 33, 20, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 59 x 33 x 20 x 247 = 115418160
Therefore, the lowest common multiple of 354,396,240,494 is 115418160.
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.
354 x 396 x 240 x 494 = 16620215040
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.
354 : 1, 2, 3, 6, 59, 118, 177, 354
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
494 : 1, 2, 13, 19, 26, 38, 247, 494
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,396,240,494, is 2.
Now, the common factors can be found like this.
354:2x 3x 59
396:2x 2x 3x 3x 11
240:2x 2x 2x 2x 3x 5
494:2x 13x 19
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 16620215040/(2x72)
LCM = 16620215040/144
LCM = 115418160
Thus, we can understand that the LCM of 354,396,240,494 is 115418160.
