Given numbers are 565,766,642,155,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 565,766,642,155,890 is 383295702810.
Find LCM of 565,766,642,155,890 with Prime Factorization
| 2 | 565, 766, 642, 155, 890 |
| 5 | 565, 383, 321, 155, 445 |
| 113, 383, 321, 31, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 113 x 383 x 321 x 31 x 89 = 383295702810
Therefore, the lowest common multiple of 565,766,642,155,890 is 383295702810.
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.
565 x 766 x 642 x 155 x 890 = 38329570281000
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.
565 : 1, 5, 113, 565
766 : 1, 2, 383, 766
642 : 1, 2, 3, 6, 107, 214, 321, 642
155 : 1, 5, 31, 155
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 565,766,642,155,890, is 1.
Now, the common factors can be found like this.
565:5x 113
766:2x 383
642:2x 3x 107
155:5x 31
890:2x 5x 89
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 38329570281000/(1x100)
LCM = 38329570281000/100
LCM = 383295702810
Thus, we can understand that the LCM of 565,766,642,155,890 is 383295702810.
