Given numbers are 319,805,319,280,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,805,319,280,778 is 799146040.
Find LCM of 319,805,319,280,778 with Prime Factorization
| 2 | 319, 805, 319, 280, 778 |
| 5 | 319, 805, 319, 140, 389 |
| 7 | 319, 161, 319, 28, 389 |
| 11 | 319, 23, 319, 4, 389 |
| 29 | 29, 23, 29, 4, 389 |
| 1, 23, 1, 4, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 29 x 1 x 23 x 1 x 4 x 389 = 799146040
Therefore, the lowest common multiple of 319,805,319,280,778 is 799146040.
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.
319 x 805 x 319 x 280 x 778 = 17844931073200
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.
319 : 1, 11, 29, 319
805 : 1, 5, 7, 23, 35, 115, 161, 805
319 : 1, 11, 29, 319
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,805,319,280,778, is 1.
Now, the common factors can be found like this.
319:11x 29
805:5x 7x 23
319:11x 29
280:2x 2x 2x 5x 7
778:2x 389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 11x 29 = 22330
Therefore, the value for common factors is 22330.
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 = 17844931073200/(1x22330)
LCM = 17844931073200/22330
LCM = 799146040
Thus, we can understand that the LCM of 319,805,319,280,778 is 799146040.
