Given numbers are 805,917,313,290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,917,313,290 is 1914430070.
Find LCM of 805,917,313,290 with Prime Factorization
| 5 | 805, 917, 313, 290 |
| 7 | 161, 917, 313, 58 |
| 23, 131, 313, 58 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 23 x 131 x 313 x 58 = 1914430070
Therefore, the lowest common multiple of 805,917,313,290 is 1914430070.
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.
805 x 917 x 313 x 290 = 67005052450
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
917 : 1, 7, 131, 917
313 : 1, 313
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,917,313,290, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
917:7x 131
313:313
290:2x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 67005052450/(1x35)
LCM = 67005052450/35
LCM = 1914430070
Thus, we can understand that the LCM of 805,917,313,290 is 1914430070.
