Given numbers are 550,840,539,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 550,840,539,423 is 45599400.
Find LCM of 550,840,539,423 with Prime Factorization
| 2 | 550, 840, 539, 423 |
| 3 | 275, 420, 539, 423 |
| 5 | 275, 140, 539, 141 |
| 7 | 55, 28, 539, 141 |
| 11 | 55, 4, 77, 141 |
| 5, 4, 7, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 5 x 4 x 7 x 141 = 45599400
Therefore, the lowest common multiple of 550,840,539,423 is 45599400.
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.
550 x 840 x 539 x 423 = 105334614000
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.
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
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
539 : 1, 7, 11, 49, 77, 539
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,840,539,423, is 1.
Now, the common factors can be found like this.
550:2x 5x 5x 11
840:2x 2x 2x 3x 5x 7
539:7x 7x 11
423:3x 3x 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 3x 5x 7x 11 = 2310
Therefore, the value for common factors is 2310.
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 = 105334614000/(1x2310)
LCM = 105334614000/2310
LCM = 45599400
Thus, we can understand that the LCM of 550,840,539,423 is 45599400.
